2 boneless skinless chicken breast halves (6 ounces each)
2 tablespoons all-purpose flour
In a small saucepan, saute the apple, ham, mushrooms and onion in 1 tablespoon oil until onion and apple are tender. Stir in mustard, bread crumbs and lemon-pepper. Flatten chicken breasts to 1/4-in. thickness; top each with the apple mixture. Roll up and secure with toothpicks. Coat with flour.
In a skillet, brown chicken in remaining oil. Place in an 8-in. square baking dish. Bake, uncovered, at 350° for 20-30 minutes or until juices run clear. Discard toothpicks.
