Begin by washing all your fresh ingredients thoroughly under cold water. Dice the cucumber, tomatoes, bell pepper, and red onion into uniform pieces. Set them aside in a large mixing bowl.

In the bowl with your diced veggies, gently fold in the Kalamata olives, crumbled feta cheese, chopped fresh parsley, and minced garlic. Use a spatula to combine everything evenly.

In a separate smaller bowl, whisk together the olive oil, red wine vinegar, and dried oregano. Season with salt and black pepper to taste.

Drizzle the prepared dressing over your salad mixture. Using gentle tossing motions, combine the salad ingredients with the dressing until well-coated.

Cover the mixing bowl with plastic wrap or a lid and chill in the refrigerator for at least 30 minutes.

Once chilled, give the salad a gentle toss again before serving. Serve cold, presenting it beautifully in a bowl or platter.
