Grate the cucumber using the large holes in a box grater. You can either grate it into a sheet of paper towel and then wring it out to remove the excess liquid, or simply grate it into a bowl and then squeeze out the excess liquid with your hands.
Add the Greek yogurt to a bowl and stir in the cucumber, garlic, lemon juice, salt and pepper, and the optional add-ins if using. I am quite generous with the salt. Be sure to taste & adjust ingredients to your liking.
Let it sit for at least 10 minutes, up to a few hours so the flavors mix and intensify. Serve with olive oil drizzled over top.
