Preheat oven to 400 degrees. Spray a 9” x 13” baking dish with cooking spray and set aside.

Prepare 2 small, shallow bowls, one with the liquid egg substitute or egg whites, and the other with 1/2 cup of the cheddar cheese, Panko, onion powder, garlic powder, parsley, salt, and pepper.

Season each chicken cutlet with salt and pepper, then dip into the egg, shake off excess and then dip into the Panko mixture. Coat well, and lay into baking dish. Repeat with all remaining chicken pieces.

Cover the dish with foil, and place into oven, baking for about 30 minutes, or until chicken is just cooked through. Remove foil, and return to oven for another 8-10 minutes, or until the edges become brown and crisp.

While chicken is cooking, heat Cream of Chicken soup in a small saucepan, over medium heat. Stir in sour cream, and remaining cheddar cheese, and cook until cheese has melted into the sauce, making sure to stir continuously. Thin with a tablespoon or two of chicken broth or water to thin, if the sauce is too thick.

Pour sauce over chicken and top with fresh chopped parsley, if desired.
