An all new flame-grilled patty, that is entirely plant-based, is the cornerstone of Burger King's new Impossible Whopper. The Impossible Whopper is served on a fresh bun and layered with an Impossible patty, fresh tomatoes, crisp lettuce, rich mayonnaise, pickle slices, onions and ketchup.
Vegan or vegetarian Burger King guests are asked to request a non-broiler method of preparation when ordering the Impossible Whopper to ensure no contact with meat while cooking.
