The Best Fish

Adapted from Miss Paula Deen's "Can't Miss Red Snapper"
Ingredients
4 (8-ounce) red snapper, rockfish, or halibut fillets, about 1/2-inch thick
1 teaspoon salt
1/2 teaspoon white pepper (or fine ground black if you don't have white)
1 cup chopped onions
1 green bell pepper, chopped
1/2 cup (1 stick) butter
1 Tbsp Worcestershire sauce (or more to taste)
1/2 a red bell pepper, finely chopped
1 cup freshly grated Parmesan

Directions
Preheat oven to 350 degrees F.
Saute onion and green pepper in 1-2 Tbsp butter until they stop releasing moisture. Spread the onions and pepper in a 13 by 9-inch glass baking dish and place the fish on top. Season the fish with the salt and pepper. Dot the fish with butter. Drizzle Worcestershire right from the bottle until the fish is gently coated. Bake for 12 minutes, then baste fish with pan juices. Sprinkle the fish with finely chopped red pepper and Parmesan on top and then place under the broiler for about 2 minutes or until the cheese browns.
