Preheat oven to 450 degrees F. Cut chicken into 3-by-3/4-inch strips. In a shallow dish, combine egg, honey, and mustard. In another dish, stir together cornflake crumbs and pepper.
Dip chicken strips into the egg mixture; roll in crumb mixture to coat. Arrange chicken strips on an ungreased baking sheet.
Bake about 12 minutes, or until outsides are golden and chicken is no longer pink.
