1 to 1 1/2 lbs. chicken breast fillets
1 lg. onion, sliced into rings
1/2 c. barbecue sauce
1/2 stick butter
Optional: Italian tomato sauce, Mozzarella cheese (grated)

Rinse and cut chicken into serving portions. Place in microwavable dish. Mix barbecue sauce with water to make 1 cup. Pour over chicken. Dot butter all over chicken. Place onion rings on top of chicken and sauce. Bake at High for 18 minutes, turning chicken over and checking for doneness at 6 minute intervals. Adjust cooking time for size of microwave and amount of chicken so fillets will remain tender. Optional: Excellent when served with an Italian tomato sauce and grated Mozzarella cheese.
