A fake meat that is made from fungus, but looks and tastes like chicken, has arrived in US supermarkets. In Europe, the meat substitute rivals soy burgers and similar products in popularity. "Known as mycoprotein, it is marketed under the trade name Quorn and made into a variety of products, including chicken-like nuggets, lasagna and fetticcine Alfredo - even as alternative to ground beef, called 'grounds'", according to a report by CNN.
