Begin by washing your tomatoes and cucumbers thoroughly. Dice the tomatoes into bite-sized pieces and slice the cucumbers into rounds or half moons.

In a mixing bowl, combine the diced tomatoes, sliced cucumbers, and chopped red onion.

Add the chopped parsley to the mixture.

In a separate small bowl, whisk together the olive oil, lemon juice, salt, and pepper to create a light dressing.

Pour the dressing over the salad mixture and gently toss to combine.

Let the salad sit for about 5 minutes before serving to allow the flavors to meld.
