1) Almond milk is not artificial and can be made at home
2) Soy products (including cheese, fake meat etc) are very common nowadays. Maybe not in the corner grocery of Brooklyn, but everywhere else I’ve ever shopped.
3) I would imagine that if a restaurant has hashgacha and openly states they are a Meat restaurant or a Dairy restaurant, and you see something that may look suspicious, read the menu. Most of them same “fake pepperoni” or “soy cheese.”
4) I think this whole topic is interesting but in the vein of looking for trouble.
