Cut each fillet lengthwise into 3 strips. Sprinkle fish evenly with 1/2 teaspoon seasoned salt.
Whisk together milk and mustard. Combine crushed cereal, cornstarch, pepper, and remaining 1/4 teaspoon seasoned salt. Dip fish in milk mixture; dredge in cereal mixture. Arrange fish fingers on a wire rack coated with cooking spray. Place rack in an aluminum foil-lined broiler pan. Lightly coat fish with cooking spray.
Bake at 375° for 20 to 22 minutes or until fish flakes with a fork. Serve with Curried Rice.
