Sausages always seemed such obvious candidates. Many nondry sausages are already often a majority nonmeat. They get their flavor already from plant derived flavorants. Yet mostly fake meat products are burger and chicken nugget replacements.

I've got to say, the fake chicken schnitzels are the first one that I really can't distinguish from the real chicken schnitzel. (Before the purists pour in, yes, compared to supermarket chicken schnitzel, which moreover isn't a real schnitzel anyway.)
