I usually sauté for about 10 min. over high heat. 2 TBLS of extra virgin olive oil, a little butter and turn up to high heat. Throw a little cut up onions, peppers and sauté until soft. Season the fish with your choice of seasoning. I like some S&P, some dried oregano, a little chili powder and whatever else is in the cabinet. Crush up the dried herbs to release the flavor more.
Sauté 5 min on one side and then turn, I then take 1/2 lemon and then squeeze over fish while it is cooking on the second side. You will know when the fish is cooked when it is starting to seperate. As stated above you don't want to over cook, since the fish will continue to cook off the heat.
ENJOY!!! Nothing better than fresh fish!
