Inspired by Guy himself, this pastrami burger is served with ketchup, pickles, Swiss cheese, grilled onions and spicy brown mustard.

Celebrate the holiday anytime with a turkey burger featuring a stuffing center (made with plenty of sage). The patty is roasted (instead of grilled) and topped with a cranberry and bourbon compote, as well as lettuce and tomato.

After this lamb burger is cooked to perfection, it's topped with Gruyère cheese, roasted red peppers, arugula, curry ketchup and a yogurt-dill sauce.
