Steps

1. 1

   Begin by preheating the broiler in your oven. Next, prepare a large shallow baking pan by coating it with oil.

2. 2

   In a small bowl, combine onions, pickles, mustard, butter, 1/4 teaspoon of salt, and 3/4 teaspoon of pepper. Mix well until all ingredients are evenly incorporated.

3. 3

   Place the fish in a baking pan with the skin facing down. Sprinkle 1/4 teaspoon of salt and 3/4 teaspoon of pepper over the fish evenly. Spread the butter mixture onto the fish. Broil the fish 5 to 6 inches away from the heat source until it is cooked just right, which should take about 4 to 6 minutes.
