Healthy Tzatziki is a Greek sauce or dip that started in Southeastern Europe and the Middle East. While there are many variations, its most common components are Greek or strained yogurt, cucumbers, salt, and olive oil. It has a creamy texture that is accentuated by using garlic, vinegar, or herbs such as mint, dill, or parsley. Any day is a day for eating tzatziki, but it's ideal on hot and dry days due to its fresh, piquant, and refreshing flavor!
