Broil it.
Put an oven rack on the highest shelf setting up close to the broiling elements. Turn oven setting to BROIL.
Put fish filet in baking pan or casserole dish. Sprinkle with whatever spices you want on both sides. I like adobo.
Chuck it in there for 4 min per side on the oven rack closest to the heating element on top. (depends on thickness of the fish. Should flake easily with a fork when done.)
There. Enjoy!
