My favorite soup for autumn:

Hearty Potato-Sauerkraut Soup

8 C chicken or beef broth 1 can of condensed cream of mushroom soup, undiluted 3 medium potatoes, cut into small cubes 3 medium carrots, chopped 1 large onion, chopped 3 stalks of celery, chopped ¾ lb smoked Polish sausage, cubed 1 C chopped cooked ham 2 T vinegar 2 t dried dillweed ½ t pepper 8 oz. fresh mushrooms, sliced (if you like mushrooms)

Put it all in a big pot and cook until the vegetables are tender, about 4-5 hours.
