Prepare the Vegetables: Trim both ends of the English cucumber and cut in half lengthwise. Slice the cucumber into ¼-inch thick half rounds. Halve the grape or cherry tomatoes and finely slice the red onion. Soak onion slices in ice water for about 5 minutes for a milder flavor.

Combine the Ingredients: In a medium bowl, gently combine the chopped cucumber, halved tomatoes, and soaked red onion slices. Use a spatula to ensure even distribution.

Make the Dressing: In a small bowl, whisk together olive oil, red wine vinegar, honey, kosher salt, and black pepper until emulsified.

Dress the Salad: Pour the dressing over the vegetable mixture and gently toss to coat evenly.

Add Fresh Herbs: If desired, stir in chopped fresh herbs like parsley, dill, or basil using a gentle folding motion.

Chill or Serve: Serve immediately or chill in the refrigerator for 30 minutes to 1 hour for enhanced flavors.
