I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!

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 love making scones, and my Mum passed on this wee hint which makes my scones even better.

When the scone recipe calls for milk, use half milk and half water. For some reason, the water makes the scones extra light with the added bonus that it drastically cuts down on your milk usage.

Save on trips to the shops during a chocolate craving, with the most dangerous chocolate cake recipe in the world! It’s called Five Minute Chocolate Mug Cake.

Ingredients:
4 tbsp flour
4 tbsp sugar
2 tbsp cocoa
1 egg
3 tbsp milk
3 tbsp oil
3 tbsp chocolate chips (optional)
Small splash of vanilla extract

Method:
Add dry ingredients to a large coffee mug, and mix well. Add the egg and mix thoroughly. Pour in the milk and oil and mix well. Add the chocolate chips, if using them, and vanilla extract and mix again. Put your mug in the microwave and cook for three minutes at 1000 watts. The cake will rise over the top of the mug, but don't be alarmed! Allow to cool a little, and tip onto a plate if desired. This can serve two if you want to feel slightly more virtuous.

And why is this the most dangerous chocolate cake recipe in the world? Because we are now only five minutes away from chocolate cake at any time of the day or night!

Watching my 'non-Simple Savings' sister unpack her groceries this week made me realise how much my shopping habits have changed in the year since I discovered Simple Savings. I used to love supermarket shopping, wandering the aisles for hours, one of this, one of that.

Some products I just don't buy anymore include:

• Liquid handsoap - I now make my own (my first SS project from the Vault). Saves $40/year.

• Spray and cooking oil - I buy 4L of good olive oil on special for about $20 and use a refillable hand pumped spray container (from House, $15 - will last years). I used to buy cans of olive oil spray at about $3.50 each and by changing how I buy oil, I am saving $100 per year.

• Cleaning products - are now missing from my list - we use bi-carb and vinegar and other simple Vault tips.

• Dishwashing cleaner - has gone too. We use citric acid, which I normally keep for my yearly lemon cordial making.

• Soft drinks and cordials - are rarely bought now - we use juice as you would cordial, and have changed our habits in favour of water.

• Yoghurt - we make EasiYo using packets bought in bulk from GoldenGlow online. Saves about $150 a year.

• Eggs and vegies - in the back yard!

• Condensed milk, Yogo, cake and pancake mixes - we M.O.O. ('make our own') using Vault tips.

• Icypoles - M.O.O. using tinned fruit juice or other - search the Vault!

• Magazines - I never buy new, just pick up the free supermarket recipe brochures or occasionally buy some gardening ones from the op shop.

• Junk and pre-prepared foods - we buy a lot less in favour of having our own 'sausage roll make-athons' or other baking with the kids.

As well as noticing the presence of many of the above things in my sister's shopping, I also noticed she buys small quantities of lots of items I now buy in bulk. Each week she has to mentally or physically check if she 'needs another of...', where I buy large amounts from the supermarket and other cheaper sources - and then don't need to think about it again for at least six months. These types of products include:

Washing powder (I'll never buy less than 20kg, and with the Vault advice to reduce our amount per load, this is lasting ages!), teabags, coffee, shampoo, dog and chook food (from pet supplier every six months), ham and meats(buy large piece of ham and store in ham bag per Vault tip - saves at least $50 a year over my previous habit of buying little cute packets of 50g each), bacon (buy from ALDI and freeze), dishwashing powder (ALDI brand is MUCH cheaper than the Finish tablets we were using - saves us $150 a year at least. I buy 12 months supply on one of my ALDI runs), cheese (buy larger amounts less often and freeze if necessary), rice (10kg bag much cheaper), jelly crystals (I bought 5kg bag at IGA last week - makes 20 serves for same cost as three individual packets), tinned fruit, soup, tomatoes and other products (from SPC outlet), nappies, paper towel and toilet paper (I buy lots when on a fabulous special). Fruit and veg I buy from the greengrocer, the market or grow my own. Meat is from the butcher, chicken from the poultry shop and fish from the fishmonger once every three months.

I could go on for every grocery item - nearly everything has changed in 12 months. This is even without noting the savings from changing products - for example, I used to think myself very clever if I bought my Uncle Toby's quick oats on super special for $2.00 per kg box - until I discovered I can buy Home Brand, which I cannot fault, for $1.00 a kilo all the time. Same for most basic products.

With changes like these to my grocery shop and to our home loan, insurance, shopping habits and so on, Simple Savings has saved us thousands of dollars in our first year of membership. Our lifestyle has actually been RICHER since SS. I didn't set out to change my shopping habits - I just started by making handsoap and buying Home Brand porridge oats - but suddenly I have realised how large this change has been. If I see you at the supermarket with your milk, bread, 8 large packets of toilet paper, 6kg of the super special meat, 10kg of rice and three-litre containers of vinegar, I'll know you caught the bug too!

Through my job working at one of the major supermarkets, I have learned all kinds of tips and tricks to save money! Next time you visit a supermarket, bear the following in mind:

• You can save up to 50% on Sara Lee products by buying our house brand bakery items instead - they are made by exactly the same company.

• The meat is no longer as good quality and has gone up slightly in price. I would suggest going to a butcher instead and paying less for better quality.

• In-store baked items are marked down from 40-80% two days before their use-by date (this does not include bread or donuts)

• Buy bulk and buy less often. For example, if you drink coffee, wait until the BIG tins are on special and buy three or four. This will last you for ages and save you $40 and upwards on coffee alone in the long run!

• If an item seems a bit sparse towards the end of the week, chances are there is actually heaps out the back and it is going on special on the Monday, so wait to make your purchase then if possible.

• For those living alone, take another look at those frozen meals. They may look expensive at first glance at between $4 and $6 but then go and price the meat and all the vegetables. Remember also to take into account how much you have to throw out after a few days through not using them!

• If you want to see who makes what, look at the back of the pack to see which company owns it. Visit the Australian Stock Exchange (ASX) website and find out which other 'mini-companies' it has under its belt. They often compete with their own brands!

For many people juggling work, family and study, time is the most important saving they can make. I work four days a week, have a three-year-old and studied part-time for a diploma for a year. I got by with these time-saving tips:

1. Lowering my expectations for the house. I don't need a spotless house, but a tidy and lived-in home.

2. Doing my housework little and often, rather than spending huge amounts of time tidying up. I do things like:

- put my little one's daycare bag together for the next day as soon as we get home in the afternoon.
- cook my lunches (pasta and sauce, muffins and so on) once a week and freeze them.
- put my lunch box together from the freezer in the evening.
- clean the toilet by putting a teaspoon of Napisan in it each night. It soaks overnight and the bowl is clean with the next flush.
- do laundry when enough for a load accumulates so we don't have a sudden clothes drought, then an avalanche of laundry to do and put away.

3. Exercising on a stationary bike in front of the TV in the evenings after my little one is in bed.

4. Programming our DVD recorder once a week (Sundays when we get the new TV guide) so I don't miss my favourite shows.

5. Filling cereal bowls with water if I am rushing and have to leave the breakfast things. This makes them easier to clean later and stops ants.

6. Trying not to double handle things. Rubbish goes straight in the bin, meat is put in meal size portions in plastic bags and frozen as soon as it gets home, magazine subscriptions go straight to magazine rack when they arrive in mail.

7. Leaving rooms better than when I arrived, so the need to tidy doesn't build up. It only takes five minutes to put laundry from the floor to the hamper, make the bed, wipe a bench, replenish the toilet paper.

8. Recruiting my little one to help - she's only three but she can put dirty dishes in the sink, put toys away in her room, dirty clothes in the hamper.

9. Shopping for groceries by myself in the evening so hubby can watch his TV shows in peace and I am not tempted to go to other stores as only the supermarket is open. Also many things are marked down at that time.

10. Trying to do three things for myself that make me feel happy each day, like listen to podcasts while I do the housework.

11. Writing the shopping list progressively through the week so I can pick it up and go when it's time to do groceries.

12. Storing the bedding in storage containers under each bed so it's quick to make the bed, especially when changing my little one's wet sheets in the middle of the night.

13. Shopping for presents at sales during the year (online or in stores) so I don't need to go to crowded stores during the Christmas rush.

14. Not beating myself up if I find lifestyle changes tricky at first - I am afterall human!

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.

I had moved into a home with an old kitchen and the stovetop needed a really good clean. I tried everything to shift the baked on grease from the rings that surrounded the coil hotplates but to no avail.

My friend suggested removing the rings and soaking them in Napisan and hot water. I actually used a generic brand nappy cleaner and it worked just as well. To my utter surprise, it removed what must have been 20 years of baked on grease. The stove looks brand new! I then did the same with the grill and oven racks, and they too came up sparkling and shiny.

For maintenance, some vinegar in a spray bottle cuts through any grease or grime left on a stovetop after cooking. But beware of vinegar on or near marble, as it eats right through it!

I thought this hint would be particularly useful for anyone moving into a rental property or having to clean their rental property before they move out. You'll save on cleaning products and get your bond back! And don't throw out pots and pans covered with grease or grime. Give them a Napisan treatment and save dollars.

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!
