We all know how convenient it is to grab a packet of cake mix off the supermarket shelf, but you can save a lot of money by making your own. This recipe is really easy to make and you can store it in the fridge for up to three months or for longer in the freezer.

Ingredients:

250g self raising flour
185g caster sugar
2tbsp milk powder, skimmed or full cream
125g butter

Method:

Sift or process all dry ingredients until combined, and then rub in or process the butter.

To make the cake add:

2 eggs
1tsp vanilla essence
1/2 cup water

When these ingredients have been added to the cake mix, beat the whole lot until combined. Bake at 150C - 180C for 30 minutes if making one cake, or 20 minutes for smaller cakes. For variety, add coffee, cocoa or anything else you like. This is as good as shop bought cake mixes and half the price!

I took on the $21 Challenge, and won! However, my husband was a rather grumpy participant; he loved the savings but not the lifestyle during Challenge week. As he goes away regularly, I decided that every night he's not home for dinner would become a $21 Challenge night for the kids and I - all meals must be made from ingredients I already have at home, and I can only use ingredients that have not been allocated for other meals. This saves money and gives me a night off cooking, as my Challenge meals are usually simple affairs, sometimes as easy as pancakes or toasted sandwiches.

The true value of the $21 Challenge became apparent when a friend was recently diagnosed with a severe form of leukaemia. She is a married mother of four boys and is embarking on a long therapeutic journey that will hopefully lead to a full recovery. As a way of helping her family, the parents at our school have banded together to make all their meals for the next three to six months. As they are a large family, with an above average food requirement, I was unsure how I could afford to help feed them each week. Thankfully, my husband was away the week my friend was diagnosed, so the kids and I lived off the $21 Challenge that week and all leftover money was put into making meals to freeze for my friend's family.

We now do the same thing whenever my husband is away – it's a great gift over the Christmas break to know that I can afford to cook and freeze meals for my friend's family, and look after my family at the same time. Thank you.

I am 22 years old and on a low income, but am well on the way to saving for my first house! I developed a simple system that keeps my savings goal at the forefront of my mind and encourages the support of those around me.

I've always found it hard to save, but one day I got a big piece of cardboard and wrote 'My House Deposit' at the top. On the right hand side I cut out images of a house, a kitchen and a loungeroom that I would love to own one day. On the left hand side I drew a giant thermometer and on the side wrote the figures $0 to $40 000 ascending, just like on a real thermometer. Whether or not I need $40 000 is irrelevant; I look at this table every day and whenever I save another $500, I colour in with a red crayon up to the amount on the tally. I use hints from Simple Savings, such as making my own lunch every day and not buying clothes if I don't need them and now whenever I make a purchase I think of my house deposit and how much I want it far more than a coffee or new shoes!

An unexpected bonus of having this chart is that I've found my family and boyfriend have become aware of my goals and I get lots of support along the way. This visualisation technique really does wonders, and most importantly you are making a concrete agreement with yourself and you stop losing sight of your goals. I'm already a quarter of the way to reaching mine!

Why buy lunch? With recipes as good as this, there's no need! I make this egg slice every few days to take to work, and I thought you might like to try it too.

Ingredients:

2 cups vegetables – just about anything will do. Leftover roast vegetables, steamed vegies, wilted salad... even raw stuff like grated carrot or chopped up tomato.

1/2 cup leftover meat, for example, bacon, fish or chicken

4 eggs, beaten

Grated cheese

Method:

Spread the vegetables and meat over the bottom of a greased square baking dish. Pour over the beaten egg, top with grated cheese and bake at 170C for about 30 minutes.

I take a quarter of this slice and some salad to work every day – it's yummy hot or cold. Thanks to the wide variety of vegetables you can use, no two slices are the same. It costs less than a dollar to make and the vegetables and protein keep me going for hours.

Making potato wedges at home is much cheaper than buying them frozen from the supermarket. I use my OXO Good Grips apple divider (bought from a kitchen shop) to cut up a 5kg bag of spuds. I give the spuds a wash before cutting them up into eight wedges and one cylindrical wedge (the kids all fight over these ones). After popping them in boiling water for a couple of minutes I put them onto paper towel to dry, then into freezer bags. These are quick, economical and you can vary the seasonings in different bags, and have them on hand in the freezer for a quick snack or side dish.

When I see the new ads on television for Watties 'NEW HOMESTYLE MASHED POTATOES' for the microwave, I just about laugh myself of the couch. I have used this system for many years, for a fraction of the price! Using an ice cream scoop, put single servings on your baking tray and freeze. To remove, gently twist the baking tray and they will 'pop' off. Place the required number of servings in one of those 'recycled' plastic bags that all us Simple Savers have stashed away and place in freezer. When they are required there's no need to defrost, just put them in the microwave (covered) and 'zap' for one minute per scoop. My kids love them with an egg for breakfast! Quick, very low cost, no nasty preservatives and yummy. Not to mention a lot more convenient than going to the supermarket and spending your hard earned dollars on more prepackaged junk you and your family don't need. Enjoy!

This super basic mince recipe saves me up to $100 a month on takeaways, thanks to the convenience of having meals already 'half made'.

All you need are:
2kg minced beef
2 cups of red lentils
2 tbsp of vegetable stock powder, or four vegetable stock cubes
1 tsp dried garlic granules
1 dsp dried onion flakes
4 cups of water.

Place all the ingredients into a crockpot and cook on high for two hours, stirring every 30 minutes. It should be thick, aromatic and an unattractive brown colour (don't let this worry you!).

One batch costs just $13 to make and is enough to serve as a base for seven meals for our family (two children and two adults). This saves heaps of money and time too. I usually freeze the mince in margarine tubs, as that seems to be the right amount for one meal for our family.

The meals I made are:

1. Piemaker pies.
   Allow one heaped tablespoon of basic mince per pie. Pour the mince into a small saucepan and add a large spoonful of gravy powder, or a dessertspoon of cornflour and some Vegemite for colour. Heat and stir until thickened. Spoon into pastry cases and cook in the piemaker.

2. Mexican enchiladas.
   I use Mountain Bread or make my own crepes. Lay the bread or crepes in u-shapes in a large baking dish. Mix the mince with an equal amount of tinned or home-made refried beans. Spread the mixture in a sausage shape down the middle of each crepe, fold each side of the crepe over, sprinkle with grated cheese and bake at 180C until the cheese is melted and bubbly. Serve on a bed of rice, topped with natural yoghurt and some salsa.

3. Stuffed capsicums.
   Halve enough capsicums for half or one per person. Spoon the mince straight into the capsicums, top with some mashed potato, pumpkin or sweet potato. Sprinkle with cheese and bake for 40 mins at 180C. Kids love these as the capsicum sweetens when baked.

4. Baked spuds with topping.
   Allow one potato of appropriate size per person. Cook in the microwave according to manufacturer's instructions. Split a cross in the top and pile filling into the opening. Top with natural yoghurt or sour cream and chopped, sauteed bacon. Allow one large tablespoon of filling per potato. Mix the filling with one tin of baked beans and heat in a small saucepan before pouring on to the potatoes.

5. Spring rolls.
   Mix about four tablespoons of mince mixture with a packet of cooked and cooled Two Minute Noodles, some shredded carrot, and 1/2 teaspoon Chinese five spice. Using filo pastry sheets or spring roll wrappers, fold a small handful of filling into each spring roll. Spray liberally with cooking spray and bake at 180C for 20-30 mins.

6. Greek pasta bake (Pastito).
   Heat a container of mince mixture with a 400g tin of peeled tomatoes. Cook enough macaroni for your family and drain well. Mix with the meat mixture and spoon into a large baking dish and top with your favourite white sauce or cheese sauce. Sprinkle on some grated cheese and bake for 40 minutes at 200C.

7. Shepherds pie.
   Add any vegetables of your choice to the mince mixture. Place into a baking dish and top with mashed potato, pumpkin or sweet potato then bake until heated and the potato browns.

I leave for work at 7.30am and get home at 6.30pm, but I still need to prepare dinner for my husband who starts night shift at 5pm. If I turn on my slow cooker at 7.30am, the food is sometimes overdone by the time he gets up at 3.30pm.

To solve this problem, I have purchased a cheap plug-in timer, just like the one people use to turn on their lights when they go on holiday. My cooker now comes on during the day and dinner is perfectly cooked by 3.30pm! This saves on power because the slow cooker is not turned on all day.

I had never considered my lifestyle to be particularly excessive, but when I found myself facing large debts and unable to make headway, I had to take control. Using the methods below, I managed to reduce my debts by $30,000 in twelve months.

Bill paying and budgeting:
I began making regular monthly payments into a savings account - which I called my ‘debt reduction’ fund. At the same time, I started to put weekly amounts in labeled envelopes. These envelopes were to cover all of the regular bills; meaning I no longer came under stress when they were due, and I didn’t need to touch any of the savings in my debt reduction fund.

I began a Christmas tin, paying $20 per week into it. While it may not be ideal to keep large sums of money in the home, for me it was preferable to paying more fees to the bank for opening yet another account.

I clear out my wallet every night and put all my coins in a jar. This alone gives me an extra $50 a month to take to the bank.

Food and grocery shopping:
Instead of takeaway food, I began substituting with one of the following:

Spaghetti (five meals per pack for $1.50) with bolognese sauce (two meals per can - $2.50)
Rice (eight meals per pack - $1.50) and canned chilli-con-carne (two meals for $3.50)
Savings approximately $20 per week.

I make sure I eat either frozen broccoli, cauliflower or peas five nights a week, at a cost of $0.60c per meal. I buy all my steak and meat in bulk and freeze in portions.

I get a box of slightly over ripe tomatoes ($3.00 for 5 kg - on special from the local fruit shop) and boil them (skins on) with onion, salt and pepper and a dash of chilli sauce. This sauce makes even the cheapest steak taste delicious, and is great with chicken too. I freeze the sauce in single portions.

Chicken drumsticks are cheap and often on special. All you need to do is roll them in flour and cook on an oven tray until golden. A quick, moist and tasty meal (two drumsticks per person) for less than $1.00.

Potato chips at $3.50 per bag are both expensive and very unhealthy. A cheaper option is to cut a $1.50 loaf of Lavash bread into triangles, dust with paprika or lemon pepper (spraying with a little oil to coat) and cook in oven until golden and crunchy. Add the home-made tomato sauce as a dip and save another $2.00 - $3.00.

I am self employed and work a minimum of 70 hours per week. It would be so easy to succumb to fast food when I am tired, but to curb the temptation I make a large lasagna (without pasta) or a salmon and rice bake; both meals with plenty of vegetables and freeze in portions. All I need to do when I get home is zap in the microwave and eat, and have my own tasty, balanced fast food meal (15 minutes to defrost and cook). Each batch I make gives me eight meals for each recipe, and as they have some of the same ingredients, it is easy to make both at once.

My recipes are delicious and low fat and I am happy to share them if anyone would like them. They cost only around $2.00 per complete meal and all use fresh vegetables.

I make my own burgers by buying mince, making thin patties and grilling, then freeze cooked, in portions. They cook super fast from the freezer with two minutes in the microwave. A quick, low fat hamburger with lettuce tomato and beetroot - $1.50 a hamburger. You can add some zapped frozen home-made tomato sauce for a really tasty treat.

I have my entire shopping list saved on my computer as an Excel spreadsheet and have the prices for each item entered. When I want something, I just enter the quantity (the spreadsheet automatically adds the total each time I input an amount) and know beforehand how much the whole bill will cost. I then look at the total and question whether I really need an item, or just want it!

By doing this, I also know when the supermarket adds a few cents (far more regularly than many people realise - usually 20% - 50% of items weekly, from upwards of $0.03c to $0.40c). I buy regular goods on special (enough for three months supply) and choose generic brands for things like tissues and toilet paper (1,000 sheets of this is the same price as 250 sheets name brand)! I also know when a special is really a special and when it isn’t, which is quite often. I take a calculator shopping and work out the best buy in quantity. Bigger is not always cheaper, and it really is good advice to never shop hungry. I have my weekly grocery budget and any savings go into the account.

I used to buy my lunch and a drink for around $8.00 each day. Now I make my own lunch each day - sandwich, fruit and a large bottle of lemon cordial. Otherwise I take a bowl of Country Ladle soup and a roll. One can gives me two meals for just $1.25 each, with my $0.60c roll. It is healthy, fills me up and saves me $6.00 a day - another $30 a week in my savings account.

There are always two large bottles of lemon cordial made up in my fridge. I only keep fizzy drink for times when I am expecting guests. I put bottles or cans in an hour prior to their arrival. If it is not normally there, I don't drink it. It costs $0.10c for a glass of healthy water based drink, as compared to $1.00 for unhealthy sugar based drinks - what would you rather have?

I save $10 a month on washing powder by reducing the amount I use each load by half.
You know by now where that extra $10 saving goes!
I am always organized for birthday and Christmas gift wrapping - I buy one bolt of wide, colourful paper (from Cello paper) for between $50 - $100 every 15 years. Based on usually giving 40 presents each year, instead of having to buy 40 sheets of gift paper at around $2.50 each, my bulk buying gives me an extra $100 a year in my savings account.

Reducing phone bills:
I now save $70 per month on my previous average mobile phone bill, simply by not making calls on impulse, and calling on a land line wherever possible. That extra $70 a month goes in the savings account. I also reduced by home phone bill by $210 per month once I realized where all the charges were going - on checking my email every time I dialed up. Now I only connect to the Internet once a day and that $210 each month goes into the savings account.

Entertainment:
My entertainment habits have also changed. Instead of paying $50 a time on the pokies, whenever I get the urge now, I put $50 into a tin for my next visit to the bank - it saves $100 - $150 from being frittered away each month. To keep control of my alcohol consumption, I would line empty bottles on my kitchen window sill and clear weekly. Doing this, you see it daily and unconsciously count the value - plus, do you want the neighbours to see how much you drink?? This saves me another $50 a month for my account. Instead of opening a can, now when I get home I have a really large lemon cordial. Then if I still feel like a drink, at least I have taken the edge off the need to relax and I will only have one every few days.

One last golden rule - put away $50 per month for ‘mad money’ - just for you to use for something special.

I paid off $30 000 in one year by using these exact tips and many more. The relief is amazing and now I save the same way.

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.
