As discussed above, the amount of salt you put on a raw beef patty will likely bring the sodium content of that patty to at or above that of the Beyond Meat patty, unless you like to (or have to) eat unseasoned beef patties. I’ve made burgers with Beyond Meat patties several times and they are pretty much pre-salted. They definitely do not need extra salt, and I didn’t add any. I did put a slice of American cheese on it though.
Back to the topic of taste, I’ve tried the Beyond Meat hamburger and the bratwurst at home, and the hot Italian sausage at a local sausage place. The hamburger has a very meaty texture but the taste doesn’t quite have the beefiness of a real burger. The bratwurst was quite good, had kind of the same texture of a bratwurst sausage (maybe without the little bits of gristly bits I guess) and the same spice flavor of a bratwurst. I don’t remember that much about the hot Italian because I got it covered with peppers and onions and mustard. I liked them all but wasn’t completely fooled by the taste. They do a pretty good job w/the texture though, and the bratwurst mostly tasted like a bratwurst - the spices probably help.
