It all starts with a hot dog. Toss it in a sweet-tasting bolillo roll. Dump some pinto beans, onions, and chopped tomatoes on it, cover it up in guacamole and cotija cheese, then drizzle on some ketchup, mayo, and mustard to finish. Garnish it with a yellow chile. Thus, you have the glorious Sonoran dog. Sometimes you might even be lucky enough to get the dog wrapped in bacon, depending where you go.
Originating in Sonora, Mexico around 50 years ago, hence the name, the famed dog (occasionally known as the Mexican hot dog) can be found in Tucson, metro Phoenix, and very few other spots around the Grand Canyon state. You can keep your Chicago dog, Windy City. We got our own. These are some of the best around town.
