Why should we eat leftovers?

Because there are some wonderful dishes made out of leftovers: leftover roast chicken can be made into chicken noodle soup or curried chicken salad, for example. Leftover chili can become part of a chili dog or chili stuffed baked potato. Of course it saves money to use food instead of throwing it out, but it is also fun and challenging to find ways to use yesterday's leftover food.
