Grate the cucumber using a box grater or food processor, then squeeze out the excess liquid using a clean kitchen towel or paper towels.
In a mixing bowl, combine the Greek yogurt, grated cucumber, minced garlic, lemon juice, olive oil, and chopped dill.
Stir well to combine all the ingredients.
Season with salt and pepper to taste.
Chill in the refrigerator for at least 30 minutes before serving to allow the flavors to meld together.
Serve as a dip with pita bread, veggies, or as a sauce for gyros or grilled meats. Enjoy!
