Have you been to any Buddhist country (Vietnam,Thailand India,etc) and tried any of the faux-chicken/beef/pork/fish dish? It isn't as real as Beyond Meat probably (since it is not made by scientists but thousands of years of practicing vegetarian) but is quite delicious.
We went to a Chinese restaurant the other day that is known for having vegetarian versions of almost every regular American Chinese restaurant dish. They used some kind of fibrous fake meat for the General Tsaos chicken that was very convincing. Maybe seaweed based?
I don't doubt it. They are probably just taking simple soy proteins and cooking them with whatever, just like we would cook meat. Not produced in some lab. I have nothing against this and appreciate it.
