Start by thinly slicing both cucumbers and radishes, aiming for uniform, delicate rounds that emphasize their crisp texture.
Place the sliced vegetables into a large mixing bowl, spreading them out evenly to prepare for tossing.
Finely chop fresh dill and sprinkle it over the vegetables for a fragrant, herbaceous layer.
Zest the lemon directly over the bowl for bright citrus aroma, then cut it in half and juice one lemon, filtering out any seeds.
In a small bowl, whisk together lemon juice, olive oil, honey (if using), salt, and pepper until the dressing is well combined and slightly emulsified.
Pour the dressing over the vegetables and herbs, then gently toss everything together until evenly coated and vibrant.
Adjust seasoning with more salt and pepper if needed, then let the salad sit for a few minutes to allow flavors to meld.
Serve the salad chilled, with a fresh sprinkle of dill on top for presentation, and enjoy the crisp, tangy freshness.
