The Rebel Whopper® features a plant based patty, flame-grilled just like the classic Whopper®, giving it the irresistible smoky, BBQ flavour you know and love. Loaded with crisp fresh lettuce, ripe hand-cut tomatoes, onion, pickles, mayo and tomato sauce on a toasted sesame seed bun. It’s 100% Whopper®, 0% Beef. You’ll have to taste it to believe it. Powered by The Vegetarian Butcher. The Rebel Whopper® is not vegetarian due to the plant-based patty being cooked on the same grill as beef patties.
