Veggie Shack

What is it?

Plant-based and built around a vegetable, grain, and herb patty, this burger gets topped with provolone, greens, tomato, and vegan mayo on a potato roll. Unlike Shake Shack's mushroom-based 'Shroom Burger, this one goes for a more straightforward veggie profile instead of a fried, cheese-filled center. The patty is meant to hold together on the grill, where it picks up a light crust outside and a softer, grainier bite inside. Since it comes with dairy cheese, it's vegetarian rather than vegan, and it sits as a permanent menu item at most Shake Shack locations.
