One of my favorite winter soups is the kitchen sink type.
I keep a large plastic container in the freezer. Little scraps of meat go in, a tablespoon of this leftover vegetable a cup of another... When the container is full, I dump it into a soup pot add some more meat if needed, vegetables, potatoes, maybe tomato sauce and seasonings... It is different each time and it is even better the next day!!!
I have even thrown in leftover noodle dishes into the container... When it all gets mixed together in the soup pot it just seems to blend together so nicely!!!
