Cut chicken into strips about 3 inches long and 3/4 inch wide.
In a small mixing bowl combine the egg whites and the 1 tablespoon honey. In a shallow bowl combine the cornflake crumbs and pepper. Dip chicken strips into the egg white mixture, then roll in the crumb mixture to coat.
Place in a single layer on an ungreased baking sheet. Bake chicken in a 450 degree F oven for 11 to 13 minutes or until no longer pink.
Meanwhile, for sauce, in a small bowl stir together the 1/4 cup honey, the mustard, and garlic powder. Serve with chicken. Makes 4 servings.
