Lidls sell wiener schnitzels (German favorite basically pulverised pork that's breaded. Other varieties and the like).
Thought to myself oooh, make a sandwich out of it. All cooked and lovely but it gets quite greasy, and it can also be quite tough.
Cue the sandwich completely falling apart, tomato sauce everywhere and me trying to finish off a meal like a caveman, not good.
Sticking your wiener in a sandwich is not a good idea.
