Lay a sheet of heavy-duty foil in a 15½ X 10½ X 1 ″ jelly roll pan. Brush foil with butter, margarine, shortening or salad oil.
Sprinkle fish with salt or seasoned salt, lemon juice and, if you like, a tiny bit of herb, such as dried basil leaves.
The distance of fish from source of heat varies with ranges and with thickness of fish filets, steaks or dressed whole fish. Here is the general timetable to use as a guide, but test fish for doneness with a fork.
Broil filets from ¼ to 1 ″ thick about 2 ″ from heat for 8 to 10 minutes. Do not turn.
Broil steaks from 1½ to 2 ″ thick about 2 ″ from heat, 10 to 16 minutes, turning once.
Broil dressed whole fish 3 ″ from heat if fish is thin. If thick, broil 6 ″ from heat. Cook 5 minutes on one side, turn and cook 8 to 10 minutes longer.
Serve on heated platter at once, garnished with lemon and chopped parsley.
