Smoked haddock cut into chunks, add rice and cook in 50/50 orange juice and water.
Salmon trimmings with cream cheese in filo parcels, make a 'sauce' of mango chutney mixed with apple sauce.
Do you have a steamer?
Wrap a piece of salmon in foil - put butter/oil, mushrooms, herbs, spring onion in the parcel. Put in the steamer with new potatoes, green beans and baby corn - steam for 15 mons.
Mackerel - buy whole, get some 'tropical' veg, mango, pineapple even akee, either fresh or tinned, stuff the fish cavity with the fruit, wrap in foil and bake -this works on the BBQ too.
Kedgeree.
My mum used to cook smoked haddock in milk, just put the fish in a pyrex dish, cover with milk and dot with butter and bake for 20-30 mins serve with crusty bread to mop up the milk (I'm lactose intolerant so don't do this myself).
Salmon, freshly cooked makes a surprisingly substantial sandwich.
Smocked salmon trimmings go well with egg, so make an omelette, or separate the yolk and white, add the trimmings to the white and lightly whisk with the trimmings, put the white with salmon in a frying pan, make a hole in the centre and add the yolk - this is great for a weekend brunch.
