I used to do the same kind of thing, put all the bits and pieces of leftovers in the freezer - veggies in one ziplok, meat in another. Saute an onion, add the frozen stuff and some potatoes and cover with v-8 juice, cook an hour or so, heavenly homemade soup. My son loved it, he would come home from school and go "Mmmmmm, refrigerator soup"!
