I've made it into a few different curries.
Served with pasta, sometimes include broccoli, sometimes a small amount of tomato sauce, often just some garlic, onion and olive oil. Or with other added seafood (various shellfish usually).
Into a fish pie, sometimes with other mixed fish (mostly cod or whiting, sometimes smoked haddock) or some prawns. (And can do this with pasta instead of coated in mash or coated in pastry with potato of some sort on the side).
PLain with veg (boiled carrots, steamed brocolli or wilted spinach usually) and hollandaise sauce, spuds on side.
Cajun seasoning on top before baking/grilling/frying, served with rice or potato and some stirfry veg with Cajun spices.
Chinese-style, with some ginger, soy, spring onions, chilli, and five spice. On rice or noodles and with stir fried veg.
Thai red or green curry. (As opposed to the more Indian curries I started with at the top).
