Meat Balls in Buttermilk Sauce Recipe

Put the ground chuck, onion, green pepper, celery, rice, salt, pepper and egg into large bowl. Work together with hands until well mixed. Divide into 12 portions; roll each into a ball. Place in a greased 2 quart casserole. Place the soup, buttermilk and liquid from the mushrooms in a bowl and beat until smooth. Pour over the meatballs, along with the mushrooms. Bake in a 350° oven for 1 hour. The extra gravy is good to spoon over baked potatoes. Yield: 6 servings.
