Food to power a walk around the world

National Geographic Explorer Paul Salopek is on a 24,000-mile, transcontinental journey and he's traveling the slow way: on foot. In this installment, he talks about the local foods he's eaten along the way. He tells host Marco Werman about some of the dishes he's tasted, from a meat dumpling stew in the Palestinian West Bank to fresh fruits and vegetables gathered on a Turkish farm to pizza in rural India.
