Preheat oven to 400°. Combine cornflakes, sesame seeds, paprika, salt & pepper; set aside. Brush 3 oz. uncooked chicken breast, pounded thin, with 1 Tbsp. skim milk; then coat with cornflakes mixture and place in non-stick baking pan. Repeat with remaining chicken breasts. Dot chicken with 2 tsp. reduced-calorie margarine and bake 15 minutes or until done.
