I like mine on the grill. This saves putting extra heat in the house in summer.

Coat each fillet with extra virgin oil, better for the heart than butter.
Sprinkle with your favorite seasoning. I just like a little Kosher salt and fresh pepper, adding too much seasonings takes away the flavor for me. Wrap the seperate fillets in aluminum foil and grill for 7-9 minutes, depending on size of fillets, on each side. serve hot.

If you don't have oilive oil you can substitute butter but it has a tendency to burn if you don't watch the fillets.
