01 - Using a sharp knife, thinly slice the cucumbers and radishes. Combine them in a large salad bowl and set aside.
02 - In a separate mixing bowl, whisk together the Greek yogurt, extra virgin olive oil, lemon juice, chopped dill, minced garlic (if using), salt, and black pepper until smooth and well blended.
03 - Pour the dressing over the sliced cucumbers and radishes. Toss gently to coat all the vegetables evenly.
04 - Taste and adjust the salt and pepper as needed to suit your preference.
05 - Let the salad rest in the refrigerator for 10 minutes to allow the flavors to meld, or serve immediately garnished with additional fresh dill.
