For the best flavor, use full-fat Greek yogurt for the tzatziki. If you don't have fresh dill, dried dill can be used, but fresh is highly recommended. You can add pitted Kalamata olives or crumbled feta cheese for extra Greek authenticity. This salad is best served chilled after allowing the flavors to meld for at least 30 minutes in the refrigerator.
