Wash the cucumber thoroughly, grate it, and squeeze out the excess water.
Mix the grated cucumber, minced garlic, lemon juice, olive oil, salt, and pepper into the Greek yogurt and blend well.
Add the chopped dill (herb) and mix again, then let it sit in the refrigerator for about 30 minutes to set.
Serve on a plate, drizzle with a bit of olive oil, and garnish with herbs.
