Rashad Jones samples some of the best smoked barbecue sandwiches from around the country. In St. Louis, Mo., Rashad hangs with a retired cop who is making a smoked pork belly BLT that's a delicious work of art. Next, he visits a deli in Oakland, Calif., that's dishing out a generous smoked brisket sandwich with a homemade tapenade. Finally, Rashad hits a San Antonio joint where they make a sandwich featuring brisket, pork belly, and mac and cheese all in one bite.
