A typical Gyro, notice the tzatziki sauce.
You might be thinking, ‘Gyros? They don’t have milk in them.’ But don’t let it fool you, the signature tzatziki sauce used in gyros is made out of yogurt, and guess where yogurt comes from? Milk. Gyros typically have spiced, grilled meat (usually a mix of lamb and beef), wrapped in pita bread with toppings like tomato, onion, tzatziki sauce (a yogurt-based sauce with cucumber and garlic), and sometimes lettuce.
