Microwave chuck, garlic & onion in Ultra 21 2 Qt. Casserole with Colander for 4 minutes. Pour off fat and transfer mixture to 2 Qt. Casserole. Stir in remaining ingredients and cook on half power 18-21 minutes, stirring several times. Cover & let stand 5 minutes. This makes enough sauce to adequately cover 1 lb of Spaghetti. I always use thin or linquine.
