Start by washing all your fresh ingredients thoroughly. Dice the cucumbers, tomatoes, bell peppers, and red onion into uniform pieces, aiming for about ½-inch cubes. Place the chopped veggies into a large mixing bowl.

Next, enhance the flavor of your salad by incorporating the kalamata olives, crumbled feta cheese, chopped parsley, and minced garlic into the bowl with the diced vegetables. Gently stir the mixture, allowing the olives and feta to intermingle.

In a small mixing bowl, combine the extra-virgin olive oil, red wine vinegar, dried oregano, and a pinch of salt and black pepper. Use a whisk to blend all the ingredients together until the dressing is smooth.

Pour the freshly whisked dressing over the salad mixture in the large bowl. Gently toss the ingredients together to coat all the vegetables and feta evenly.

To allow the flavors to meld beautifully, cover the bowl and place it in the refrigerator for about 30 minutes.

Once the salad has chilled, give it a gentle toss to refresh the ingredients. Taste and adjust the seasoning with additional salt and pepper if necessary. Serve this vibrant salad in a large bowl.
