At the Rome 'N Chariot truck in Mississauga, Ontario, a husband and wife team are bringing authentic Italian comfort food to the masses. Featuring Meatball Sliders with housemade marinara sauce and a loaded Porchetta Sandwich stuffed with Italian sausage. Then we travel to Indianapolis, where east meets west at the Spice Box truck. With Indian delights such as Chicken Tikka Masala and a Spicy Wrap with mint chutney, these guys put the Indian in Indiana. Next up is Molly's Eats in Edmonton, Alberta where locals are lining up for a smorgasbord of international comfort food; Mac and Cheese with Pulled Pork & Bacon and a Columbian inspired platter with plaintains, pork belly and sausage. Lastly, we're in Portland, Ore., where The PBJ's cart has redefined the classic sandwich. Tasty versions include Orange Marmalade and Thai Curry or Goat Cheese with Kalamata Olive bread.
