Blacken them. Awesome taste and a good show. Just do it outside.
My new go to.
I second the do it outside. I dry the fillets, lightly brush with olive oil and season generously with zatarans blackening seasoning. I have an electric nonstick skillet, I wished it got a little hotter, but it works really well for the task and is nice to take outside and use.
Stay away from thick pieces.
