Tantuni is a traditional street food dish from Mersin, consisting of thinly sliced beef or lamb that is seasoned with Turkish spices and herbs, usually cooked with onions and tomatoes. The combination is cooked in specially designed tantuni pans.

Traditionally, the dish is served rolled in lavash, with ground sumac and a lemon wedge on the side. Since every tantuni chef has his own method and secret technique of preparing the dish, it is said that the flavors of tantuni are never the same.

Tantuni was originally created as a poor man's dish - it's very nutritious because it consists of meat with a lot of fat stuffed into bread. Some believe that the name of the dish refers to the sound that the meat and spices make when they are brought from the rim of the pan to its center.
