Gyros, sometimes anglicized as a gyro in some regions, is meat cooked on a vertical rotisserie, then sliced and served wrapped or stuffed in pita bread, along with other ingredients such as tomato, onion, fried potatoes, and tzatziki. In Greece, it is normally made with pork or sometimes with chicken, whilst beef and lamb are also used in other countries.

Pita or pitta is a family of yeast-leavened round flatbreads baked from wheat flour, common in the Mediterranean, Levant, and neighboring areas. It includes the widely known version with an interior pocket, also known as Arabic bread. In the United Kingdom, Greek bread is used for pocket versions such as the Greek pita, and are used for barbecues as a souvlaki wrap. The Western name pita may sometimes be used to refer to various other types of flatbreads that have different names in their local languages, such as numerous styles of Arab khubz (bread).
