this might be a California thing but I love fish tacos, normally I like serf perch but ANY fish that's not real oily will work you want a clean tasting fish,
I like a simple beer batter or sometimes I'll just get a bag of the Cajun cornmeal and then deep fry it
then I make a sauce 1/2 cup Greek yogurt plain, 1/2 cup mayo, a diced jalapeno or pablano pepper and 1/2 tsp of each of oregano, cumin, and dill, and a tsp cayenne add some lime juice to thin it up to the consistency you want, chop up some cabbage warm up some corn tacos or fry them however you like, add the fish, cabbage and sauce then squeeze a little lime juice on it and go to town, just keep it simple and they are the best
