Arby's announced on Tuesday that starting Sunday, August 27 the fast-food chain will debut an all-new smoked turkey leg, complete with salt and brown sugar, smoked and then slow-roasted to "perfection."

The turkey leg will be available in nine different regions across U.S., including Los Angeles, Pittsburgh, Phoenix, Seattle, Denver, and Atlanta.
