We have a lot of leftovers at work sometimes & I like to find ways to incorporate them into other recipes or create something new with them in order to get them used up so they don't go to waste. Especially in these trying economical times. One thing I often do is use leftover casseroles to make soup. They tend to make for a heartier and tastier soup than just the norm. What do all of you like to do with your leftovers?
