Planning out your weekly meals is both easy and kinder on the wallet as you end up chucking less away. If you're having a roast chicken, why not use up the carcass and trimmings by planning to make chicken soup and chicken sandwiches the next day? If you've got loads of leftover veggies kicking about in the fridge, use them to knock up a really big batch of soup and freeze the surplus for days when you can't face cooking. And once a month or so, you should go through your store cupboard and use up any packaged or tinned food that's getting close to its use-by date. Just making small changes like this can really make a big difference to the amount of food waste you produce.
