Cut skate into square measuring about 1-inch. In a zipper top plastic bag, combine all remaining ingredients. Add skate to sealed bag and marinate in refrigerator for 30 minutes.
Preheat broiler of barbeque grill. Place skate on rack or grill positioned about 4 inches from heat source. Cook for 6-8 minutes. After 3 minutes, brush the top with some of the marinade, turn pieces over and continue to cook until pieces flake easily when tested with a fork. Serve immediately.
