In Queens, N.Y., Michael Symon gets in touch with his Greek heritage with a classic lamb and feta cheeseburger, and then he sinks his teeth into an Italian-style burger stuffed with smoky mozzarella and prosciutto. In Houston, Texas, he finds a rabbit-meat hot dog with chile pepper toppings so spicy there's a release waiver to sign when ordering it. And finally, in Phoenix, Ariz., Michael places an order at a food truck that hitches up a custom smoker to deliver hot smoked meats inside inventive grilled cheese sandwiches across the Arizona desert.
