Pat fillets dry with a paper towel and sprinkle evenly with salt. Working with 1 fillet at a time, dip in the egg to coat, letting excess egg drip back into the dish. Then dredge in the cornmeal mixture, turning to coat both sides. Transfer to the prepared rack on the baking sheet. Repeat with the remaining fillets. Coat the tops of the fillets with cooking spray.
