Crockpot Meatball Stroganoff
(from a friend at Babycenter.com -- publisher unknown)

1 can Cream of Mushroom soup
1 14.5-ounce can beef broth
1 18-ounce package frozen fully-cooked meatballs (about 35 meatballs)
8 ounces sliced fresh mushrooms
1 cup sour cream
1 Tablespoon flour
1/3 cup water

Combine soup and beef broth in a crockpot.  Add meatballs and mushrooms, cover and cook on low for 6 to 8 hours.  Combine sour cream, flour and water in a bowl.  Stir mixture into meatballs, cover and cook on low for 10 minutes before serving.  **I served on top of egg noodles.**
