On this trip, Guy Fieri's unhinging the jaw for some stellar sandwiches and big-time burgers. In Palm Desert, Calif., an Italian market-deli is pilin' up the porchetta, and a funky burger joint is adding their own over-the-top twists. And in Nashville, a Vietnamese spot is makin' the bomb banh mi and a mind-blowing steak and rice bowl.
Guy Fieri invites three of the best sandwich makers on Diners, Drive-Ins, and Dives to compete in a sandwich showdown. First, the chefs make a spicy sandwich using just nine ingredients or fewer. Then for a chance to earn up to $20,000, they build a stacked and jacked sandwich that includes the sammie whammies listed on the pins they don't knock down in a round of grocery bowl.
