This very special Food(ography) takes an in-depth look at the sandwich, literally the greatest thing since sliced bread. From its inception at the poker table to its international hits like the spicy Mexican Torta, the hearty Chicken Parmesan, or the proper English Tea Sandwich, this show's got you covered like cheese on a tuna melt. And yes, that is a Sea Urchin Sandwich that Chef George Mendes put in your lunchbox.
