Our Plant-Based Whopper® features a plant-based patty - flame-grilled just like the classic Whopper® - loaded with crisp fresh lettuce, freshly sliced tomatoes, onion, pickles, with ketchup and mayonnaise* on a toasted sesame seed bun. Plant-based patties cooked on the same grill as meat patties. *Mayonnaise contains eggs. Not suitable for vegans.
