Take 4 boneless, skinless chicken breasts and place in a 9 x 13 pan. Smother in Barbecue sauce. Cover pan with foil and bake at 350 degrees for 1 hour. Take chicken out and sprinkle your choice of Colby or mozzarella cheese on top. Replace foil and place chicken back in the oven just until cheese is melted! Super yummy and easy!
