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.

After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.

My husband was dying of lung cancer. He wanted his ashes scattered at sea and, being a practical man, discussed other details. He did not think much of church services and a eulogy delivered by a person he did not know.

He died in my arms at home and the next morning he was picked up by Sommerville Funerals. (Most people are unaware that they may have some time with their loved one before the body is collected.) A private cremation was arranged and I collected my husband's ashes for his 'celebration of life' at our home. All our friends arrived, charged their glasses, sat or stood on our front lawn and listened to his story that I had written a few days before. We played his favourite music and people stayed all day. My husband loved a great party and this was no exception. Everyone said this was the best service they had ever attended and they were going to do the same.

Incidentally, the only cost was the private cremation fee. Nothing like some of the very high fees I was quoted.

At 12 years old, my daughter is already helping our family save money on snacks using her Simple Savings skills! With five children in the house, we do a big shop just once a month and are careful to make our food and treats last until the next shop. Recently we were nearing the end of the month and getting low on food. I arrived home one day to find my daughter baking biscuits. 'They're Doos!' she told me. 'You always said if there was nothing in the cupboard, we had to make do, so I made Doos!'

The name has stuck in our house and now whenever we have 'nothing' in the house for lunch boxes, snacks or afternoon tea, she just makes a batch of 'Doos' using whatever she can find in the pantry to 'make do' with. She is proving to be very inventive with her recipes and is turning out to be a real baker. She'll turn out simple but delicious treats such as honey joys, choc chip biscuits, Anzac biscuits, pikelets and pancakes in no time at all! She really has shown that you can make something from almost anything in the pantry and would be wonderful at the $21 Challenge! Here is the recipe for her latest creation, called 'Sort of Scones!'

1 cup oats
1 cup self raising flour
1/2 cup sugar
125g butter
1 egg
1/4 cup milk

Mix all ingredients together, then roll into balls and place on a greased baking tray. Bake in a moderate oven (around 180C) for 10 minutes.

I couldn't be prouder of my daughter's efforts to help us save money and keep everyone well fed. Whenever we think our parenting has a lot to be desired, it's moments like this which prove we have to be doing something right - good things do rub off too!

To help me stick to my budget, I use the 'purse system', where I allocate a certain amount of money each payday to pay for different things, for example, petrol or groceries.

I found the envelope system aesthetically unappealing and difficult to operate, so I purchased a number of small pencil cases from Office Works; they're the perfect size to fit dollar notes into and any receipts for that particular 'budget purse'. I have a red case containing money for my groceries, a black case for my petrol and so on. They are also attractive enough that I use them as my wallets for these purposes; unlike envelopes, I am never too embarrassed to pull a case out and carry it into a shop. The cases cost $8.00 each but they motivate me to stick to a budget - a huge long-term saving!

We had the chance to travel overseas several years ago but had to save $1000 to make it happen. On one income with two small children it seemed impossible. Then I had the brainwave - I didn't have to save $1000, I had to save $1.00 a thousand times! This was so much easier - a generic brand product at the grocery store, a chocolate bar at the petrol station and so on, soon added up and the savings contributed to a great family holiday.

Skint but stylish. That's how I like to think of my lifestyle, because it is such fun to live on the smell of an oily rag without anyone else knowing! Eighteen months ago, although in recovery from depression, I found myself many thousands of dollars in debt and with several accounts having been sent to collection agencies. I was also 31kg overweight and at risk of cardiovascular disease and Type 2 diabetes. The excess weight (not to mention the stress!) was also making my arthritis worse. I was no longer able to work in my former profession and, as I was in my early sixties, I wasn't able to find other work and was on Centrelink (Social Security) benefits. I have since been transferred to the Age Pension. I knew I had to make some drastic changes, and pretty darn quickly too! I had just a few things going for me:

• My Visa card was a debit, not credit, card.

• My account was with a credit union, rather than a bank, and fees are much less.

• I was knowledgeable about nutrition.

• I was willing to face unpalatable facts about myself and make lifestyle changes.

With this small armoury, I prepared to do battle! The first thing I did was to sit down with all the paperwork, and list all the accounts, personal loans and the total. I nearly had a heart attack right there and then, but with the information, I was able to draw up a projected payments schedule. I contacted all the collection agencies and told them how much I proposed to pay each fortnight until all were paid. I did the same with private lenders. Nobody turned my proposal down; it really is true that, if you get in contact and show willingness, most lenders will give you time to pay. They would rather have their money than you in jail!

Step 2 was to organise payment of my electricity account by direct debit from my pension - what you never have, you never miss. Once the phone bill was paid off and reconnected, I did the same with that too. In all, my debt reduction program was going to be about $200 per fortnight, or roughly 34% of my pension and Centrelink allowances. Since my rent costs another 34%, the remaining 32% had to stretch to cover food, cleaning materials, clothing, pharmacy costs over the pharmacy allowance, fares for trips outside walking distance, presents, postage, life insurance and credit union fees (direct debit from my credit union account), occasional small charitable donations and the occasional small treat.

Step 3 was to go on to a sensible eating program (not a fad diet) that would help me to lose weight, bring my blood glucose and serum cholesterol levels into the normal range. A low GI, high carbohydrate, moderate protein, low-fat pattern fitted the bill in all respects. The challenge was: could I do it on $50-$75 per fortnight? The answer is yes! I make my own wholemeal bread, soups, skim milk yoghurt and lots of interesting dishes from many countries, based on grains and vegetable proteins, and stock up on tinned oily fish for essential fatty acids when on special. I have red meat and poultry only once or twice a fortnight and the rest of the time my proteins are derived from legumes, eggs and low-fat cheeses. It's just as well that I like oats! I drink two litres of water a day and make my own herbal teas from homegrown herbs. I don't buy soft drinks and buy leaf tea rather than tea bags, as it's better value per unit serving. I find whole fruit better all round than juice as a rule.

Step 4 was to get mobile! I walk, because I can't afford gym membership, and walking can be done by those who can't jog. Being out in the open air blows away the blues too. Having won a free pedometer, I wear it and try to reach 10,000 paces a day. I also started a vegetable garden and this saves me money where it counts, on vegetables, as well as being another source of fresh air and exercise.

Is it working? Is it what! In the last financial year I paid off $5000 in debts on the pension alone, and am on track to achieve the same amount this financial year. I lost 13kg in the same period - a nice, sustainable rate. My blood glucose level is normal, my serum cholesterol almost so, although because of familial hypercholesteraemia, I need some medication to help with that. I am continuing to lose weight slowly but surely and have much more endurance and less pain. My GP is nearly as stoked as I am. I take care of my clothes, believing that 'well-pressed is well-dressed', so my appearance doesn't give me away either. Occasionally I earn a little money from magazine contributions and this usually goes towards seeds or something else for the garden, but occasionally I restock the pantry with staples. I make my own cleaning products with such simple substances as vinegar, bi-carb of soda, washing soda crystals, soap scraps, eucalyptus oil and - wait for it - Worcestershire sauce (cleans brass and copper a treat, and one nearly always has it handy). I turn my appliances (apart from the fridge) off at the wall when not in use and have noticed a difference in my power usage. All my incandescent light bulbs have been replaced with long-life fluorescent ones, and by crafty use of acrylic-lined curtains I keep my house cooler in summer and warmer in winter. I pile on the clothing layers in winter and wear cool clothing in summer. If I'm watching TV in the winter, I cover my legs with a woollen rug and put on another cardigan if necessary, rather than turn up the heater.

Because I can't afford much for presents, I give of myself. A nice present is a 'book of vouchers', made attractively and containing such redeemable coupons as: 'This voucher is good for two hours' ironing... or an evening's baby-sitting... or... whatever!' Very few people say no to home-made goodies either. It makes me feel truly wealthy to give someone a loaf of bread still warm and fragrant from the oven, or a jar of chutney.

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!

I only need to shop for food once a month and am saving $3000 per year on feeding our family of six.

With four children, I was spending at least $800 per month on shopping, so I came up with a plan to try and cut costs. I went through recipe books and chose meals that I was going to cook for dinner. I wrote a list on an A4 page for every day of that month and what I was going to cook for each day. Then, on another page I wrote all the food items that I needed for the recipes I had pre-chosen and that was my shopping list for the month.

The best thing is I now knew what I was cooking every day, without walking to the fridge and thinking 'what am I cooking?' I also put the A4 page of what we were having for dinner on the fridge and the family knew what we were having each day without asking me!

To start with I went shopping every fortnight for food, but now I do it once a month and only spend $550 each month.

Before I began this routine, I was spending $9600 per year on food for four children and two adults - now I am spending $6600 per year! The extra $3000 we save each year goes into our children's bank account, which they just love!
