3 lb. hamburger
1 1/2 c. croutons
1 can mushrooms, chopped
1 med. onion, chopped
1 c. Carnation milk

Mix ingredients together and form into balls. Brown. (I usually do this using the broiler.) Put into a casserole dish and cover with 2 cans cream of mushroom soup diluted with 1 cup milk. Bake at 350 degrees for about 45 minutes or bubbly hot. Could also use a crock pot. Makes quite a large amount.
