Gyros is one of the most popular Greek street food dishes, consisting of meat such as pork and chicken (in Greece) or lamb and veal (popular in other countries) cooked on a vertical spit. The meat is sliced in thin shavings and is then usually placed in a pita bread along with sauces such as tzatziki and vegetables such as tomatoes, onions, lettuce, and cucumbers.

Gyros is derived from the Greek word gheereezo, meaning to turn, referring to the constantly rotating vertical spit on which the meat is cooked. Some believe that gyros originated during the time of Alexander the Great, when his soldiers skewered the meat on their swords and cooked it over a fire.

Others claim that gyros was introduced to Greece in 1922, with the refugees from Constantinople and Smyrna. Many of the refugees became merchants and opened their shops with tiny holes in the wall, where gyros was sold. After WWII, gyros gained popularity and spread to Europe, Australia, and the United States.

Today, gyros is known as one of the most popular street food varieties around the world.
