Cindy Pawlcyn, chef and founder of the Napa Valley’s Mustards Grill, shows us how she makes her famous BBQ American Lamb Burger, one of the signature dishes on her menu. She prepares a flavorful BBQ spice mix that she blends into the ground lamb patties. The burgers are served with a sweet and spicy BBQ sauce, grilled onions, sharp cheddar cheese, basil aioli, and arugula.
