The Sonoran hot dog is a style of hot dog that originated in Hermosillo, the capital of the Mexican state of Sonora, in the late 1980s.
[1][2] It is popular in Tucson,[3][4][5][6] Phoenix,[7] and elsewhere in southern Arizona.
[8] It consists of a hot dog that is wrapped in bacon and grilled, served on a bolillo-style hot dog bun, and topped with pinto beans, onions, tomatoes, and a variety of additional condiments, often including mayonnaise, mustard, and jalapeño salsa.
[9][10] The Sonoran hot dog is prepared and sold by vendors called "dogueros" at street carts.
[1] It was estimated in 2009 that over 200 places in Tucson purveyed the Sonoran hot dog, and that Phoenix had even more.
