Morrisons (at Cambourne, Cambridgeshire) were doing some cracking deals on salmon recently - bought an entire salmon for £22. If you see this offer in your local morrisons, please confirm availability.
The fishmonger chopped the head and tail off as wife didn't like the idea of doing that!
Can then chop up into individual slabs and freeze what you won't eat today.
So easy to cook: smother in butter, wrap in foil, bake.
When cooked, salmon with scrambled egg is also nice ;-)
