I am saving around $100 a month on my grocery bills, thanks to a few simple changes to our family meals. I wanted to reduce our food bill and after some thought came up with the idea of making two nights per week a '$2 Dinner Night'. For example, one night we will have something like toasted baked bean sandwiches or stuffed baked potatoes; the other I use up all the leftover vegetables in the fridge to make a self-crusting quiche. This reduces the amount of food we waste and the kids love it. Even the simplest meals can be delicious and filling and the savings we are making from our twice-weekly $2 dinners are well worth it!

As a new member, I have saved $150 in my first week, thanks to the $21 Challenge! I thought I was careful with money until I discovered this site and realised how I could further improve my spending habits. I decided to give the $21 Challenge a go and it is now Thursday and I haven't been to the shops yet!

I have become a problem solver due to the fact that I must use what is in the fridge/freezer and pantry. I nearly buckled when my four year old wanted 'pink milk' and I had run out of Nestle Quick but no problem in the end. I found some rose pink food colouring and with just one drop - presto, pink milk! It does take some preparation because you are cooking from scratch but it is all worth it when your family tells you that the dinner you made tonight was the best, and is there any more?

My other dilemma was to use the three zucchinis in the crisper, so I made them into a slice. It was so easy to make and I had every ingredient on hand without even trying!

Zucchini Slice (serves 4-6)

3 zucchini (grated)
1 onion (grated)
1 potato (grated)
4 slices of ham/bacon (chopped)
1 cup of cheese (grated)
6 tablespoons flour (plain)
3 eggs
salt/pepper

Put all ingredients into a big bowl and mix really well. Pour into a quiche dish and cook in the oven for one hour at 160C. If you are vegetarian, simply leave out the ham. Simple, delicious and super cheap!

I am no longer wasting leftover avocado, thanks to this simple storage tip! I have always loved avocado but could never use a whole one in one go. I would use about a quarter for my lunch but by the time I went to use the rest it would have gone brown and didn't look very appetising! Avocados can be quite pricy so the expense of wasting so much was very annoying. Then my new partner, who is chef told me how to stop the browning! I didn't realise but the longevity of avocado is due to light. He advised me to wrap the avocado in aluminium foil and then wrap it in cling wrap and put it in the fridge. To my surprise it really works! Now I get to enjoy ALL my avocado and save heaps too!

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.

Three weeks ago we ended up without a cent to spend on groceries and the money situation for the following week was only slightly better. We had to eat, of course, so I raided the pantry and freezer and managed to get by on what we had. We were also running out of laundry powder and toilet paper so I rationed out these things to make sure we made it through until we could afford to stock up. It meant using less laundry powder per wash and a few less squares of toilet paper each visit, but we got through the week without having to buy anything, saving around $300.

The following week we had only $30 for food shopping. I still had things I could use up in the pantry and fridge/freezer, and the rationing of the laundry powder and toilet paper meant we wouldn't need to buy more until the next week. So I spent our $30 surplus for that week on milk, fruit and vegetables.

Last week we were back to normal but my two weeks of poverty made me realise just how much money I can save each week by using less of everything and trying to use up what I already have in the fridge and pantry. Over two weeks I had managed to NOT spend about $570 and I had also cleared out a stack of canned beans, canned tuna and sardines, frozen vegetables, frozen meat and frozen loaves of bread that were taking up space in my pantry and freezer.

I bake everyday because I enjoy baking and my family (5) enjoy eating. This has saved us thousands over 11 years. We have paid cash for 2 new cars and we have owned our house outright after only 5 years of mortgage. To save money grow a vegetable garden and flowers for enjoyment. Shop for specials and buy in bulk but not so much that it expires before you can use it.

My husband is self-employed and over Christmas and New Year we were waiting on a payment that had been due in November. I had not done any shopping for over a month, and we felt like there was nothing in our pantry, especially my five kids who repeatedly moaned ' there's nothing in here!’

Of course, that wasn't the case. It's amazing what you have stashed away in containers or hiding at the back of each shelf. On a closer inspection, we found dried beans and lentils, flour, sugar, cous cous, rice and lots of other bits and pieces.

We managed to feed our family of seven on the 'nothing' in our pantry for another two weeks. We are lucky enough to keep chickens, and have a very basic vegetable garden, so all I really needed to purchase was milk. We made pancakes, pikelets and scones, and even a chocolate cake with the cocoa we found - these snacks kept the kids, and hubby, very happy!

We survived until our very overdue payment finally arrived. We have now decided that we will eat the cupboard clean every month, as this encourages us to save money by using what we already have and by not allowing things to go out of date.

Instead of paying for one expensive doona, and the dry cleaning costs that come with it, buy two or three cheap doonas, pin them together at the corners, and put them into the same doona cover.

Because cheap doonas are thinner, you can wash them one at a time in your washing machine, and you can also adjust the warmth. When the weather starts getting warmer, just take one doona out of the cover and put it away in the cupboard.

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 have decided I want a house which I can clean in minutes and I don't want any more energy or money draining clutter that makes it harder to control. The more I have the harder it is to control and the more motivation I need to contain it. 'Less is more' is my new mantra! I am applying this principle to my finances as well - when I buy too much it is such a burden and I don't have the motivation to stay on top of all the bills. Therefore, less is more - more energy, more money and more happiness!
