How to Make It
Cut chicken into 20 (1/4-inch-thick) strips. Combine chicken and buttermilk in a shallow dish; cover and chill 1 hour. Drain chicken, discarding liquid. Combine chicken and flour in a medium bowl, tossing to coat.
Preheat oven to 475°. Place baking sheet in oven.
Combine egg and egg white in a small bowl. Combine crushed cornflakes and next 5 ingredients (through ground red pepper) in a shallow dish.
Working with 1 chicken strip at a time, dip into egg mixture; dredge in cornflake mixture. Repeat procedure with remaining chicken, egg mixture, and cornflake mixture. Arrange chicken in a single layer on preheated baking sheet coated with cooking spray. Lightly coat chicken with cooking spray. Bake at 475° for 6 minutes or until done. Serve immediately.
