Texas Tommy is a Pennsylvanian variety of hot dog, consisting of a toasted bun filled with a split and grilled or fried hot dog sausage, crispy slices of bacon, and heaps of cheese. The earliest versions had sausages that were wrapped in bacon before being grilled, and it is suggested that Texas Tommy possibly influenced the creation of Tijuana dogs. This hot dog variety gained popularity in the 1950s, especially among housewives, as recipes for bacon-wrapped hot dogs appeared regularly in ladies' magazines. Today, it is a staple at diners in Pennsylvania, Philadelphia, and New Jersey.
