01 - Thinly slice the cucumbers and radishes using a sharp chef's knife. Place them together in a large mixing bowl and set aside.
02 - In a separate small bowl, whisk together the Greek yogurt, chopped dill, minced garlic, lemon juice, olive oil, salt, and black pepper until the dressing is smooth and well combined.
03 - Pour the yogurt dressing over the sliced cucumbers and radishes. Toss gently with a fork or whisk until all the vegetables are evenly coated with the dressing.
04 - Taste the salad and adjust the salt and pepper as needed to suit your preference.
05 - For the best flavor, refrigerate the salad for 10 minutes before serving. Alternatively, serve immediately as a refreshing side dish.
