01 - Using a sharp knife, thinly slice the cucumbers and radishes. 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 smooth and well combined.
03 - Pour the yogurt dressing over the sliced cucumbers and radishes. Toss gently with a fork or tongs 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 - Refrigerate for 10 minutes to allow the flavors to meld, or serve immediately as a refreshing side dish.
