METHOD
Wash and dry fillets. Cover with garlic butter on one side and place this side up. Place fish on broiler pan (after spraying pan with non-stick spray). Put a little water in pan so drippings don't stick and burn. Broil 5-7 minutes (on second rack level). Turn fillets (Optional-I broiled for another minute or two). Cover fillets with salsa and top with grated cheese. Return to broiler and broil until cheese is melted.
Optional--add capers with salsa layer or top with olives for garnish.
