Have you tried Burger King's Meatless burger?

The trial run in St Louis has been so successful that the Burger is being rolled out Nationwide.
The Impossible Burger contains Wheat Protein, Coconut Oil, Potato Protein, leghemoglobin, an ingredient from soybeans which is a protein that is chemically bound to a non-protein molecule called heme that gives leghemoglobin its blood red color.
Reviews say that it is almost impossible to distinguish the difference between an Impossible Burger and a regular Beef Whopper
