Trim off the two ends of the cucumber and then halve it lengthwise. Then slice it into ¼-inch thick half rounds.
Place the cucumber and sliced red onion in a medium bowl.
To make the dressing, in a small bowl, whisk together the olive oil, red wine vinegar, honey, salt and pepper.
Pour the dressing over the salad and toss gently to mix.
Gently stir in the fresh herbs, if using. Serve immediately or chill in the refrigerator for an hour or two to let the flavors meld together and then serve.
