The primary ingredient in a traditional Greek gyro is meat, typically pork, chicken, or lamb. The meat is marinated with a blend of herbs and spices, then cooked on a vertical rotisserie, which gives it a distinct flavor and tenderness. Once cooked, the meat is sliced thin and typically served in pita bread along with fresh ingredients like tomatoes, onions, and tzatziki sauce, which is made from yogurt, cucumber, garlic, and herbs. Gyro is a beloved street food in Greece and enjoys popularity around the world for its delicious flavors and satisfying components.
