And of course, I forgot....
Sardines!!
My weekly dose of oily fish, not the bog standard supermarket tinned sardines though (although they are acceptable) I've found a company in Covent Garden that stock a variety (changes from month to month) of French or portugese tinned sardines available mail order. various forms (some in olive oil, escabeche, with lemon, chilli etc. and of course, the old favourite tomato both bog standard or spicy) get the toast on, then whilst you butter it, 40 seconds in the popty ping for the fish, then mashed up with a bit of white pepper and maybe a dash of vinegar. a lunch fit for a king!
