Arrange oats in a single layer on a jelly-roll pan; bake at 400° for 5 minutes or until golden. Combine oats, salt, and next 4 ingredients (salt through pepper) in a food processor; process until oats are finely chopped. Place oat mixture in a shallow dish; place egg substitute in a medium bowl. Dip chicken in egg substitute, and dredge in oat mixture. Place chicken on a baking sheet coated with cooking spray, and drizzle butter over chicken. Bake at 400° for 20 minutes or until done.
