I love fish tacos! I use tilapia, and top with a raw Asian slaw mix and a tiny bit of italian dressing.
My husband uses haddock, lettuce, tomato and onion with a sour cream and dill sauce with a little mustard. He will probably put some kind of coating on the fish.
It all depends on what he has on hand and what appeals to him on a particular day.
I wouldn’t mind trying scallop tacos.
