buy in bulk and plan to freeze full meals. as the girls mentioned, making up a big serve of spag bol is better than a small lot that you eat some and freeze. plan to make alternative meals with it. for us, spag bol mix is made into spag bol for that meal, spag bol (frozen), pasta bake (next night) and pasta bake (frozen meals). we usually cook up a kilo of mince into spag, so HEAPS given there are only two of us. we have found cheap containers that are perfect size for us for a meal. for DH, it's a meal, for me, it's about a meal and a half. if i can't eat the extra half meal for lunch or whatever, it goes to the dogs (one advantage of fur babies). we also get the disposable metal trays with lids for freezing pasta bake (spag bol topped with white sauce) in individual meals.

we put MASSES of veg in everything. if veg is starting to look a bit wilted, we'll do spag bol or a braise, and put all the veg in it. dice it up small and throw it in. it's not unusual for us to have 7 or more vegies in spag bol...

in the end, when we have leftover veg, i'll grab a piece of pumpkin, chop up all the veg, throw it in a pot with some chicken stock, and make soup. we do this at least once a fortnight. the amount of soup depends on how much veg is starting to get beyond it's best.

in your situation, it might be better to shop weekly rather than fortnightly, or twice a week rather than once. only buy what you KNOW you will use so that you don't waste stuff. with fruit, google cake/muffin recipes that use the fruit (banana, apple, peach etc) - they are freezable so you can have a mixture of things sitting there, take them out early in the day for arvo tea or whatever...
