What is the Impossible Burger? A meatless burger that tastes like a delicious burger should but it’s made from plants. It’s primarily made from wheat protein, potato protein, coconut oil, and heme (the molecule that gives meat its color and flavor). Is it Vegan? It’s made for meat-lovers, but it’s ok for vegans too. The Impossible Burger is plant-based, but don’t call it “vegan” or “fake” anything. It’s meat made from plants. Plant based, nut-free, and dairy free. It contains gluten and soy.
