A toasted sesame seed bun comes with grilled mushrooms, onions and peppers, then you choose the rest from Five Guys’ free toppings. No patty sits in the centre, so it reads more like a custom vegetable sandwich than a burger. The vegetables are cooked on the same flat-top as the chain’s beef burgers, which is worth knowing for anyone comparing it with other vegetarian options in the lineup. Add lettuce, tomato, pickles, jalapeños, grilled onions or sauces, and it’s assembled to order.
