I have been curious about those "impossible whoppers", made from all plant materials. People say it tastes just like a regular whopper. I had an opportunity today to try a "promotional" (free) one at my local Burger King. It was, OK. As a free-burger, I'm willing to eat another one. If I have to pay for it, I'll just go with a normal whopper. I confess. I don't really see the advantage of the "meatless" hamburgers.
