I have finally convinced my three daughters that eating a healthy lunch, including sandwiches with salad, is not only good for them but tastes great too. However, soon after changing their lunch habits, I found that this method was taking a large chunk out of our budget.

Being a working mum, it was easier to stop at the supermarket on the way home and buy pre-packed salad ingredients, but I soon discovered it was adding around $55 to the weekly budget. Plus, buying cold meat to match everyone's tastes added another $40 per week. I decided it was time to cut down. After doing some homework looking for the best prices and quality, I now purchase a bag of carrots, a couple of fresh beetroot, some fresh bean sprouts and cucumbers and a variety of lettuce. I noticed that by purchasing these items late on Sunday afternoon, I can pick them up even cheaper.

I grate my own carrot, beetroot and cucumber, throw in the bean sprouts and store in the fridge in an airtight container. I tear up the lettuce leaves and mix together in a plastic shopping bag and store in the vegetable crisper where they stay fresh and crunchy all week. My salad ingredients now cost less than $10 per week and they last longer. Throw in a small portion of sundried tomatoes for my hubby and I add approx another $1.50 to my total.

Instead of buying cold meat from the supermarket deli, I now purchase a couple of extra chicken breast fillets from my Asian butchery for around $4.00; this is cheaper than ALDI or any other local fresh meat source. I cook and shred the chicken myself while tinned salmon and tuna add extra variety; a $0.69c tin of tuna covers two lunches when added to salad. I purchase mince when it is on special and make a large batch of meatballs, which are frozen and used over a period of weeks as another filling alternative. Another favourite is home cooked corn beef; rather than putting the leftovers in the fridge, I slice it thinly and freeze for another filling choice.

My three girls are now involved in the Sunday afternoon preparations. Whilst my eldest daughter is madly grating the salad items, I tear up the lettuce and my younger daughters have great fun mixing the meatball ingredients and rolling them ready to cook.

Our family of five is still eating yummy healthy lunches but for $70 to $75 a week less than before!
We also have the added bonus of spending time together while we prepare and my daughters are learning new skills too.

I pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!

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.

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.

I use a simple principle every day, which helps me save money in all areas of my life. I try to reduce my use or consumption of what I normally do by 10%. The rewards are enormous. For example, if you spend $200 a week on groceries, try reducing it by $20 over 52 weeks and straight away you have $1040 extra in your pocket. You and your family won't even notice the difference, as it equates to less than $3.00 a day!

If you apply this principle to all areas of your life - petrol, electricity, phone calls and so on, the savings are huge even though the sacrifice is not even felt. It not only saves money but also the planet by reducing your overall consumption. Once I achieve this 10% reduction, I do it all over again! Every quarter after the electricity bill comes in, I then set myself the 10% goal anew to keep myself on track and to challenge myself to reduce further. This means the $180 grocery bill then reduces by a further $18 a week and so it goes on. I have done this only to a point where it is comfortable and achievable. Because it is baby steps it is easy and fun and not painful! We have saved hundreds, if not thousands, in the last year or two and are not feeling so pressured by the mortgage rate rises. Best of all is that we haven't noticed any difference to our lifestyle.

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.

I'm saving money, time and sanity by serving dinner much earlier – here's how! With three young school children, I was finding they were coming home really hungry from school, eating up and were not hungry at dinner time. This meant I was struggling to find healthy, economical after school snacks and throwing away perfectly good dinners! The solution? I changed our dinner time to 3.30–4pm! They have a healthy, nutritious meal when they're hungry and a small snack such as fruit later in the evening. No wasted dinners, no stressed mummy! I have their dinner ready when they get home and then have more time to help them with homework. They are also helping out more with dishes and so on, which is a great help to me.

We have saved over $150 in seeds alone this past year. Instead of paying up to $5.00 for packets of seeds which may or may not sprout, we have started grabbing packets of seeds from the herb sections of Woolworths, Coles and IGA. Most mustard, coriander, fennel, cardamom or celery whole seeds that you get as a spice for cooking will sprout for you in your garden. These normally cost around $1.05 per packet and you will get a lot more seeds than if you bought them from a gardening shop. We also get the full dried peas (not freeze dried) from the soup section and have planted these successfully for three years now. They give us the sweetest sugar snap peas ever! A packet normally costs $1.53 and you get close to 100 seeds. In comparison to buy 'packet' seeds it would cost you over $12.

We also cut the ends off shallots and replant them, it takes about three weeks before they start to recover, but then you have an endless harvest of shallot leaves to use in salads. We do the same with old onions that have hidden themselves away in our cupboards and have sprouted. Plant them in your garden, let them go to seed and you will have a great seed stock for the next few years. No need to buy more!

Garlic can be done in the same way. Grab a clove and plant it flat end into the ground. After about four months you will get a great bulb of garlic from your original clove. Be aware that garlic from China or Mexico has been treated with Bromide (cancer causing agent) so only use Australian grown garlic.

Old potatoes and sweet potatoes that start sprouting can be replanted and will give a good yield. Just cut a 3cm piece around the sprouting part of the potato and plant it, from one potato alone you could get up to seven new plants.

Pumpkin, cucumber, capsicum and other vegetable seeds can be cleaned, dried and then planted out to give you more seed stock to play with. Try planting two different types of pumpkins near each other and you might get a hybrid created which tastes great. Our family had a butternut mix with a jap pumpkin and it was the sweetest tasting pumpkin we'd ever tried. We also let one or two of each vegetable go to seed so that next years planting will cost us even less. Our goal is to go totally self sufficient in the garden. So far we have an abundance of butter lettuce, silverbeet, rocket, mint, corn, tomatoes and sugar snap peas all from previously saved seeds.

Simple Savings has become a way of life. I don't have to think about saving or spending now - it just comes naturally. In the past five and a half years, we have managed to pay a whopping $150,000 (principal) plus interest off our mortgage and still live happily and comfortably. This is all due to Simple Savings.

My husband and I have three young children and our combined income is only average, ranging between $50,000 - $70,000 per year. Readers may think 'I could never do that, I would have to go without too much' or 'that's impossible', but this is not true. We don't go without; in fact we feel we do pretty well! I cannot name just one single thing that has helped us to achieve this and still be happy - it is a multitude of tips and hints, all of which can be found on your site. I have always been a Simple Saver, so for me this was not hard, but my husband found not being able to spend money willy-nilly difficult at first. These days, I am proud to say he thinks before he spends and at times even proudly tells me of his smart purchase or why he didn't purchase!

I could go on and on giving examples on how to do what we have done, where we saved money and how we used it more wisely, but that would make a book and to be honest all people have to do is log on to your site, it's all there. Focus on your goals, walk hand in hand with Simple Savings and your dreams can come true.

I have turned my love of a good bargain into something far more valuable! Whenever I am tempted to buy something I could possibly do without, I first calculate how much we would save by paying that money into our mortgage instead. For example, I recently saw a new dress on sale for $49.99 - a bargain, right? However, I paid a quick visit to a mortgage calculator website and discovered that if I didn't buy the dress and put that money onto our mortgage instead, it would take a whole month off the loan term and save us $334.39c in interest. In other words, my 'bargain' dress would really cost me over $300!

Looking at my purchases this way has become a really easy and effective way to curb my spending habit. Now I carry a piece of paper in my wallet with various prices on and I can see how much I would really be spending. It's amazing how much stronger my willpower becomes when I check my piece of paper before buying something and find out what its real cost is!
