Combine Parmesan cheese, bread crumbs and sesame seeds in a medium sized bowl. Dip chicken pieces one at a time in the melted butter then in the Parmesan cheese mixture to coat.
Place in a 9"x13"x2" baking dish. Bake at 350 degrees for 1 hour and 15 minutes or until chicken is done.
RECIPE VARIATION: Use boneless, skinless chicken breasts in place of the chicken pieces. This recipe coats 6 to 8 chicken breast halves. Decrease cooking time to 35 minutes or until chicken is done.
