I should eat more fish, but it requires the effort of getting it fresh. There's also the problem that common fish, like cod and haddock, I don't consider particularly ethical to eat at the moment, with critically low stock levels. Mackerel is surprisingly cheap, and as far as I can tell, there's still a reasonably healthy stock in the North Sea.
Tonight's dinner was mackerel with tagliatelle verdi and a fairly straightforward tomato based sauce. It was rather nice.
