I grant you no good night out is complete without one....its just not a sandwich.
No good night out is complete without a couple of Caol Ilas.
But two Caol Ilas wrapped around a pint of poachers choice does not a sandwich make
It fit's the criteria of a sandwich (even more so at 2am post pub) meat, wrapped in bread with some veg, apart from it being unleven bread I don't see the distinction from a Bacon Lettus and Tomato with mayo, you can hardly say it's a couple of slices of bread giving a dead pig a cuddle.
