The Sonoran hot dog is a style of hot dog popular in Tucson, Phoenix, and elsewhere in southern Arizona. It originated in Hermosillo, the capital of the Mexican state of Sonora, in the late 1980s. 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. The Sonoran hot dog is prepared and sold by vendors called "dogueros" at street carts. It was estimated in 2009 that over 200 places in Tucson purvey the Sonoran hot dog, and that Phoenix has even more. (WIKIPEDIA)
We walked about a mile through a suburban neighborhood (maybe not our best decision) until we ended up at this food cart that had a few patrons already enjoying their dogs. Nogales is known for their hot dogs in this area, so it was worth the trek.
The hot dog had bacon, beans, onions, tomato and mayo. Now I know that all sounds a little crazy, but it was actually really good!
