Made with the Impossible Foods plant-based patty, this burger delivers a meaty texture and savory taste that has converted countless skeptics. Customize with your choice of toppings and sauces.

Vegetarian Burger Variations

Truffle Mushroom Veggie Burger
Plant-based patty topped with sautéed mushrooms, truffle aioli, caramelized onions, and arugula. Elevated vegetarian dining at its finest.
