In a medium bowl, whisk together ¼ cup of olive oil, 2 tablespoons of balsamic vinegar, and a pinch of salt and pepper.

Just before serving, dice 1 large English cucumber, 1 cup of cherry tomatoes, and ¼ of a red onion. Pat the diced vegetables dry.

Add the diced cucumber, tomatoes, and onion to the bowl containing the dressing and toss them in.

Gently toss the salad ingredients with a pair of salad tongs until everything is well-coated with the dressing.

Allow the salad to rest at room temperature for about 10-15 minutes before serving.
