Preheat oven to 400° F. Spray an 8-inch square baking pan with vegetable cooking spray.
In a small bowl, beat egg white and water. Dip fillets in egg white, then roll in crushed corn flakes. Arrange fish in baking pan. Sprinkle with parsley, salt and lemon pepper; drizzle with butter.
Bake, uncovered, for 20 minutes, or until fish flakes easily with a fork. Serve warm.
