Saute: Season with coarse salt, pepper or herbs. Add 2 tablespoons oil or butter to skillet. Heat oil over medium-medium high, but don’t allow oil to smoke. Place filets in skillet and cook for 1-4 minutes. Shake pan occasionally while the fish is cooking to prevent it from sticking. Turn the fish over and cook for another 1-4 minutes until fish flakes easily and is opaque in the middle.
Bake: Preheat oven to 425F. Place fish in lightly oiled shallow baking dish. Season with salt, pepper, butter or margarine. Bake 6-10 minutes per inch of thickness of filet until it is opaque in the middle.
