Wash and dry the cucumbers and tomatoes. Slice cucumbers into thin rounds and cut tomatoes into wedges.

Thinly slice the red onion and soak in cold water to achieve a milder flavor, if desired.

In a large mixing bowl, combine cucumbers, tomatoes, and red onion.

In a small bowl, whisk together olive oil, vinegar or lemon juice, salt, and pepper. If using garlic, let it sit in the dressing for a few minutes.

Pour the dressing over the salad and gently toss to combine, ensuring the vegetables are coated.

Add the fresh herbs and toss again lightly to incorporate.

Let the salad sit for about 10-15 minutes to meld flavors before serving.
