Weirdly, in the US anyway, most "fast food" places have had no vegetarian protein at all on the menu. Their only main course vegetarian options tend to be salads with very low protein (and usually, only a single kind of salad out of maybe 3 will actually be vegetarian - the others will have a meat protein). It's no mean feat for a vegetarian who's traveling to find a source of protein at any of these restaurants. Before the "fake meat" products, Taco Bell bean burritos were basically the only ubiquitous option. Starbucks, and some other fast food joints, do have some egg-based protein options in the morning. So I have no love for Impossible/Beyond/whatever ultraprocessed stuff, and I'd much rather get a big bowl of black beans with some tempeh or something, but the convenience of being able to find any protein when you're pressed for time is welcome.
