Grate the radishes using a box grater or food processor, then place them in a colander and sprinkle with salt. Allow to sit for 15 minutes.

Transfer salted radishes to a clean kitchen towel and squeeze out any excess liquid.

In a mixing bowl, combine drained radishes with grated garlic, Greek yogurt, olive oil, and lemon juice. Mix until well blended.

Stir in salt and pepper, adjusting seasoning to taste.

Cover and refrigerate the dip for at least 2 hours or overnight for best flavor.

Before serving, stir the dip and garnish with mint or dill if desired. Serve with pita, veggies, or grilled meats.
