Minestrone

I love soup. Heat 2-4 cups chicken stock , add 2 or more cups spaghetti sauce and some beans (kidney, cannellini and black beans are my favorites for this) and bring to a boil. Add small pasta and cook according to package directions. Let sit off heat for a few minutes before serving.
I usually add green beans and corn and red bell pepper and will saute some carrots before adding the chicken stock if I have time. This is an excellent way to use leftover vegetables and beans.
The pasta will soak up most the liquid if there are leftovers (which are excellent topped with sharp cheddar).
