All American BBQ Chicken

2 T olive oil
1 large onion, chopped
2-15 oz cans tomato sauce
1 c red wine vinegar
1/2 c light molasses
1/4 c Worcestershire sauce
1/3 c packed brown sugar
3/4 t cayenne pepper
2-3 1/2 lbs. chickens each cut into quarters, skin removed

In 10-inch skillet, heat olive oil over medium heat. Add onion and cook until tender, about 10 minutes. Stir in tomato sauce, vinegar, molasses, Worcestershire, brown sugar, and cayenne pepper; heat to boiling over high heat. Reduce heat to medium-low and cook, uncovered, 45 minutes or until sauce thickens slightly. If not using sauce right away, cover and refrigerate to use within 2 weeks. Reserve 1-1/2 cups sauce to serve with grilled chicken. Place chicken quarters on grill over medium heat; cook 20 to 25 minutes, turning chicken once. Generously brush chicken with some of the remaining barbecue sauce; cook 20 minutes longer, turning pieces often and brushing with sauce frequently until juices run clear when chicken is pierced with tip of knife. Serve with reserved sauce. Serves: 8
