Ensure the chicken is completely dry, then season both sides with salt and pepper.
Dredge each piece first in the flour mixture, ensuring a generous coat.
Dip next into the egg mixture, allowing excess to drip off to prevent a soggy breading.
Coat thoroughly in the crushed cornflake mixture, pressing the crumbs onto the chicken to adhere well. If necessary, repeat the dipping in the egg and then the cornflakes for areas that appear under-coated.
Arrange the breaded chicken on a lightly greased, light-colored baking sheet.
Lightly spray the breaded chicken with nonstick cooking spray.
