Preheat your oven to 450 degrees. Pour soy sauce into a dish and add chicken coating it with the soy sauce on both sides. In a plastic bag combine the sesame seeds, flour, salt and pepper. Add chicken to the seasoning bag and shake to coat the chicken well. Place chicken in a 13x9 inch-baking dish that has been sprayed with the non-stick cooking spray. Lightly spray the top of the chicken with the butter-flavored cooking spray and bake in the oven for 30-45 minutes or until center of the chicken is no longer pink and the juices run clear. Makes 4 servings. Serve with your choice of vegetables and a small salad.
