That's how you know there's something off with vegans, they need to simulate meat without any meat.  Some of those burgers add beet juice so that it 'bleeds'. Saw an ingredients list on one of them, turns out (at least that version I saw) was nothing but pea protein, oils, and 'cellulose'.    The closest to 'food' type veggie burger was at least beans mashed together and fried so that it held a burger shape, but even that one felt more appropriate to have as the 'chili' on a meat burger than the meat replacement. The ones that are advertised everywhere, that's the type of thing that, in the future, will be treated as toxic.
