Place the rack in the top third of the oven and preheat the broiler.
Place fish on a lightly greased broiler pan. Brush with butter. Lightly salt and pepper.
Broil about 4 inches from heat until done, about 9 to 14 minutes. Remove to a serving platter. Serve with Brown Butter Sauce.
While fish is cooking, prepare Brown Butter Sauce.
Brown Butter Sauce
Heat butter in a small saucepan over medium-high heat. Stir until it foams and is lightly browned. Remove from heat and stir in lime juice and green onions. Pour over the cooked fish.
