LT42 perhaps I should have been a bit more precise with my wording - obviously döners will contain meat, but my point is that they’re often whizzed up with all sorts of other crap like gristle and phosphates:

It’s true that some places which call themselves “döner” that do have the meat on the spit which mostly resembles the still fully formed sliced chunks of chicken or whatever it is, but even then they’re practically without fail overly greasy crap with god knows what else in there.
Ultimately, I’ve never eaten a döner that didn’t seem like a piece of crap, while very rarely you can find an alright shawarma that won’t coat your guts with grease and give you explosive diarrhea.
