From the azcentral.com article “Serving up a special treat: Sonoran hot dogs“
For the uninitiated, Sonoran hot dogs are bacon-wrapped wieners piled high with beans, mayonnaise, cheese, onions, tomatoes — and for the more daring, mushrooms, guacamole, salsa and jalapeño peppers — all stuffed inside a fluffy white Mexican roll called a bolillo.
Bacon-wrapped hot dogs are a fast-food staple in Sonora, Arizona’s neighbor to the south. Known as “hot dogs estilo Sonora,” they are so popular, Sonorenses, as people from that state are called, eat them as often as Mexicans in other states eat tacos.
A true crossover hybrid of American and Mexican border culture, Sonoran hot dogs also have long been popular in Arizona communities closer to the border. In Tucson, scores of restaurants and street vendors sell Sonoran hot dogs. This past summer, a battle between rival vendors became so heated, the FBI got involved. In the end, one Sonoran hot-dog vendor was charged with trying to extort $600,000 from another.
