Bring a large pot of salted water to a boil. Add the orzo pasta and cook according to package instructions until al dente, typically around 8-10 minutes.
Once cooked, drain the orzo and rinse it under cold water to stop the cooking process. Let it cool completely.
In a large mixing bowl, combine the diced cucumber, halved cherry tomatoes, diced red bell pepper, finely chopped red onion, sliced kalamata olives, and crumbled feta cheese.
In a separate small bowl, whisk together the olive oil, lemon juice, dried oregano, and a pinch of salt and pepper.
Add the cooled orzo to the vegetable mixture, then pour the dressing over the top. Gently toss everything together until combined and well coated.
Fold in the chopped parsley for added freshness, and adjust seasoning if necessary.
Cover the salad with plastic wrap and let it chill in the refrigerator for at least 30 minutes before serving for the flavors to meld.
Notes
Serve the salad in a large, decorative bowl, garnished with additional feta cheese and parsley on top.
