We have friends who throw all the leftovers into an ice cream bucket in the freezer and use it once a week to make soup. I, personally, am picky about which foods go with other foods, so this would not go over well with my tastes.
I use up my leftovers once a week in a fried rice...this is especially good for wilting vegies, and little bits of meat.
I pack up leftovers in my dh's lunch, so we don't end up with too much being thrown out!
