Wash your cucumbers and tomatoes thoroughly under cool water. Slice the cucumbers into bite-sized pieces and halve the tomatoes. Place in a large mixing bowl.

In a small mixing bowl, combine olive oil, red wine vinegar, salt, and black pepper. Whisk for about 30 seconds until emulsified.

Transfer vegetables to a serving bowl and pour dressing over them. Toss gently to coat.

Let the salad sit for at least 20 minutes at room temperature to enhance flavor.
