Lots of left over chicken
3/4 stick butter, melted
2 med. green peppers, minced
2 med. onions, minced
1 (32 oz.) jar meatless spaghetti sauce (I like Stop and Shop brand)
1 lb. Mozzarella cheese, sliced

Cook onions and peppers in melted butter until transparent. Add sauce and chicken, cover and heat until hot. Half an hour before serving, put in 13 x 9 x 2 inch pan. Cover with Mozzarella and bake in a 350 degree oven until cheese is melted.
