A small place out on silver strand beach sold fish tacos and I had them about 25 years ago. They weren’t very fashionable back then, but they have gotten to be more and more so. Most places you get your choice grilled or breaded.Â
Grilled is definately healthier, so here you go.
I like white fish, like tuna but  Sea Bass and Talipia Halibut work well also.  Tuna and Thresher Shark taste like steak with a lot less fat.Â
Typically I make my “Spanked Tuna”, slice it, and then layout a display of sides for the buffet.
Or fire up the grill. Â
