The company, which boasts renowned restaurateur David Chang as one of its partners, offers a rotating menu of flavor-packed options, like a roast pork and fig sandwich, a tofu and soba noodle bowl, and a veggie burger with cheddar cheese and homemade sauces. In fact, the veggie burger is so popular that it’s been known to sell out before the kitchen even begins service. "We think the Maple Veggie Burger is special because of the satisfying mix of wholesome ingredients with the indulgent condiments of the cheddar cheese, Avocado Mayonnaise, and Beet Ketchup,” says Davies. “Vegetarian burgers can sometimes be dry and lack flavor, but our patty is flavorful and rich from the mushrooms and chickpeas. And the addictively good Beet Ketchup is tasty on almost everything!" Try the recipe below for yourself (or order a veggie burger tonight on Maple—just be sure to act quickly!).
