Wipe fish with a damp cloth; sprinkle with salt and pepper. Place fish on greased broiler rack about 4 inches from heat; broil until fish is delicately browned. Turn carefully on other side until fish flakes easily when tested with a fork. Serve fish hot with parsley butter sauce.
Parsley Butter Sauce:
Cream butter with parsley, salt, pepper and lemon juice. Spread the sauce over the cooked fish while hot.
(Note: I just bake in oven on oiled cookie sheet at about 375 degrees for approximately 30 minutes turning over once halfway through (till flakes easily with fork. I usually bake from frozen state because I get them from Schwan’s and you bake from frozen with theirs.)
