The Impossible Burger is taking over. It's been introduced at countless restaurants and fast food places and the wave seems to keep getting bigger.

In fact, if you compare the Impossible Burger to a veggie burger, the two taste nothing alike. What gives the burger that beef taste though? Its Heme.
