I don't know how long you've been living in the US, but that simply does not ring true any more. If you walk into an average M&S "Simply Food" - and these are now everywhere and they sell 20% of all sandwiches eaten in the UK each day - you will be confronted with 15-20 different sandwiches in wraps, subs and traditional bread. Not one of them will be the vision or memory you have of a thin slice of ham and a thin slice of cheese. The closest they sell to that has a decent amount of both and the sandwich is a good 2" thick. There is typically a range of options with some that are "lighter" and some which pack in more ingredients. That's for price point reasons. Even in M&S you can get a sandwich, packet of crisps and a drink for £3.50 - for that, you might be prepared to forego some salad. If you want a little more, you can, and you will pay a little more for it, and you will be sated. To me the sandwich industry has really changed over the last 5-10 years - far, far more choices.
