Po'Boy to Pit Beef: What's Your Favorite Regional Sandwich?

Some regional sandwiches hit the big time, like the New Orleans muffuletta or the Los Angeles-born French dip, while others are famous only to those who grew up eating them. From Kentucky's Hot Brown to Chicago's Italian beef sandwich, there are enough regional specialties around the country to keep a traveling sandwich eater well-fed and happy. What is your favorite regional sandwich?

Lonely Planet has a list of 20 great regional sandwiches that is a good place to start for those interested in expanding their meat-and-cheese horizons. Some are a little terrifying (yet intriguing!), like the Horseshoe from Springfield, Illinois, an open-faced sandwich made with two pieces of toasted bread and two hamburger patties piled high with cheese-sauce-smothered French fries.

Others are well-known favorites, like the lobster roll, the po'boy and the Cuban, which fans argue was either invented in Tampa or Key West — or was it Cuba? If it ever comes up, just nod and keep eating; we've found that when it comes to great regional sandwiches, emotions run deep.
