Smear it with olive oil, salt lightly, cover with chopped herbs (as lightly or generously as you like, whichever herbs you like. Mine change with my mood.) Into a 375 oven, skin side down. How long depends on how big and how thick. Check the chart in your favorite cookbook (Joy of Cooking has one).

Pan seared in olive oil and butter

Bought some on a whim (fillet), without a plan. Roasting or broiling preferred. Thanks!
