Start by washing the cucumbers and tomatoes under cold water. Peel cucumbers if desired and slice into thin rounds or cubes. Cut tomatoes in halves or dice larger varieties.

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

In a large mixing bowl, combine the diced cucumbers and tomatoes, then pour the dressing over and gently toss everything together.

Let the salad sit at room temperature for at least 20 minutes to enhance flavors before serving.

Serve chilled or at room temperature alongside grilled meats.
