In my experience the meat references are mostly referring to the functionality of the product. E.g. if I want to eat a pair of buns with some meat, cheese, salad in between I can simply look for a vegetarian "burger" and know that it's attempting to solve for that exact use-case. Best example of this I know of is probably the vegetarian hot dogs at ikea. They taste nothing like hot dogs, but boy do they taste great in a hot dog bun with ketchup.
