gyros is greek food

Origins[edit]

Though grilling meat stacked on a skewer has ancient roots in the Eastern Mediterranean with evidence from the Mycenaean Greek and Minoan periods,^[5][6][7] grilling a vertical spit of stacked meat slices and cutting it off as it cooks was developed in the 19th century in Ottoman Bursa.^[8]
Unlike tacos, gyros form part of the sandwich family and are differentiated from other hand-held semi-folded foods by their complete over-wrap but unsecured lower flap.^[9]
