I do a really quick and easy parmesan crumbed fish. DS loves it (so does DH ). Put some seasoned flour on one plate, a whisked egg on another plate, and a pile of grated parmesan on another plate. Take your fish fillets, dip it in the flour, then the egg, then the cheese and pan fry or bbq for a few minutes each side until cooked through. I usually have a salad or homemade chips with this one.

Otherwise my other fish dishes are usually seafood paella or risotto.
