Roger loves a great barbecue sandwich and when the meat's cooked low and slow and kissed with just the right amount of smoke, he rolls up his sleeves and digs in. Roger heads to The Barbecue Exchange for two sinfully delicious sandwiches - one is called Heaven and the other Hell. Both are packed with pulled pork and bacon. Then it's off to Papa KayJoe's BBQ in Centerville, Tennessee where pork, pickles, slaw and hot sauce are sandwiched between crispy corn cakes.
