If you buy the smoked salmon trimmings they are useful to cook with eggs, add them to scrambled egg or mix with cream cheese and put on crackers.
Salmon parcels are easy, get some foil, grease with butter or oil, put the piece of salmon on the foil and add whatever you like, I like a slice of lemon, some chopped spring onion salt and pepper, fold the foil into a parcel, it can be baked in the oven, put in a steamer in an air fryer or on a BBQ.
Make a tomato sauce using 1 pack of passatta, a tin of drained chickpeas and whatever spices you like, a bit of chili, salt and pepper, some cumin.
Heat in a pan and once up to boil put in pieces of salmon, push them in so they are not floating on the sauce, simmer for 10 mins.
If you have any fresh herbs, coriander or parsley or even basil, add some just before serving.
If you get some boneless smoked haddock try adding it to rice in a pan with a 50/50 mix of orange juice and water.
