This special competition is all about celebrating the sandwich, every "wich" way it may be prepared. The four competitors must get creative, starting with beef brisket appetizer sandwiches, but when two chefs make the same big mistakes, who will move on? The chefs must make entree-worthy sandwiches from pork shoulder and pate. And stacking up dessert sandwiches is so much fun, but what will the two finalists make with Thai curry paste and chocolate-covered espresso beans?
