Yeah, it's a spicy (usually) vegetarian patty made with black beans that's served up as a meatless alternative to hamburgers. Done right, they actually aren't too bad. Done badly, it's like eating dried out succotash. In either case, you'll never mistake it for the juicy goodness of actual ground beef. I look at it a lot like eating falafel (which I also like) rather than anything remotely resembling an actual hamburger.
