Pour Wish-Bone® Italian Dressing over fillets in large, shallow nonaluminum baking dish or plastic bag. Cover, or close bag, and marinate in refrigerator up to 1 hour. Remove fillets from marinade, reserving marinade.
Arrange fillets on broiler pan. Broil until fish flakes with a fork. Brush with 1 tablespoon reserved marinade, then sprinkle with bread crumbs mixed with parsley. Continue broiling until crumbs are golden.
