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 smooth and well combined.
03 - Pour the yogurt dressing over the sliced cucumbers and radishes. Gently toss until all the vegetables are evenly coated with the dressing.
04 - Taste the salad and adjust the salt, pepper, or lemon juice as needed to suit your preference.
05 - Refrigerate for 10 minutes to allow the flavors to meld, or serve immediately for a crisp, refreshing side dish.
