The creamy combination of yogurt, cucumber, and garlic makes tzatziki a refreshing appetizer that can be eaten alone, with bread, or as an accompaniment to vegetables, meat dishes, and pita wraps. It is one of the dips for which Greece is most well-known.
Making it for a large group? Try adding grated carrots to increase the quantity (1 carrot for each cup of yogurt used). They add a nice crunch and don't affect the taste.
