I am buying food more consciously with meals and a menu for the week planned. This week I have had some food that has gone off and needed tossing - some potatoes started sprouting so were tossed into the compost, some jelly in a bowl in the fridge was never eaten and some rice went to the dog. Much better than previous amounts that would be thrown away because we hadn't gotten around to eating it.
One of the things that used to be brought and regularly went off before being eaten was fruit. I would buy the fruit with the best and healthiest intentions. But it would sit in the fridge or fruit bowl and the kids, MR Gadget and I would overlook it for other snacks. So it would stay there deteriating a little more each day until it was no good for anything but the compost. So changes had to be made. I still buy heaps of fruit. But now I cut the fruit up (melons, pineapples etc) and put them into see through containers in the fridge. Because they are all cut and ready to be eaten the kids grab them out. There is no peeling or chopping so it is easy and fast for a quick snack. And because I am storing it in a clear container it is very visable and doesn't get overlooked or forgotten. I also add fruit to their breakfast cereals.
If it looks like the fruit isn't going to be eaten in time I will stew and freeze (apples, rhubarb, pears etc).
We have passionfruit vines and they produce an enormous amount of fruit each year. The kids love them but I was always having an excess, even after giving some away to friends. Then Guitar Dude had the brilliant idea of putting them in the freezer whole. They made the best frozen snack. It was just a matter of taking them out, cutting open and scooping the frozen juice and seeds out with a spoon. Big hit and no more passionfruits going off.
I have also began making fruit smoothies using fruits, yoghurt, honey, milk etc. Very refreshing and filling for an afternoon snack.
