S.B.
My hubby and son are kayak fishermen. So we eat a lot of fish.
We love, love, love this recipe for fish tacos. We have used everything from catfish, to cod, to tilapia with this one. We prefer it on flour tortillas. The sauce is a little spicy, but not too bad. Both our 4 and 2 year olds like just a little on their tacos, but not much. We also do this one with fish we baked or grilled for a healthier version.

We also like to rub the fish with a little butter, some kosher salt and a touch of pepper and then wrap it in tin foil. It's good baked, but we prefer it cooked on our grill. Again we have used all kinds of fish for this one. We have even do this and left the skin on the fish. It's more work afterwards, peeling the skin, but still yummy.
Generally I am not a huge Rachel Ray fan, but we do enjoy this recipe. http://www.food.com/recipe/rachael-rays-tilapia-with-toma... I usually leave out the Serrano peppers. And I cheat, instead of chopping tomatillos, I buy salsa verde or chopped tomatillos in the can. It's worth the time savings to me. I like Tilapia for this one best.
Catfish is usually best fried. Roll it in a half corn meal and half flour mixture with some salt, pepper and cayene.
