Bring a large pot of salted water to a boil. Add the orzo pasta and cook according to package directions until al dente, typically about 8-10 minutes.
While the orzo cooks, prepare the vegetables. In a large mixing bowl, combine the cherry tomatoes, cucumber, red onion, Kalamata olives, and parsley.
In a small bowl, whisk together the olive oil, lemon juice, dried oregano, salt, and pepper to create a simple dressing.
Once the orzo is cooked, drain and rinse it under cold water to cool it down. Let it drain well before adding it to the mixing bowl with the vegetables.
Pour the dressing over the orzo and vegetable mix, tossing everything together gently until well combined.
Add the crumbled feta cheese on top and fold it in carefully to avoid breaking it too much.
Taste and adjust seasoning if necessary, adding more salt, pepper, or lemon juice as desired.
Chill the salad in the refrigerator for at least 30 minutes to let the flavors meld together before serving.
Notes
Serve in a large bowl for a family-style presentation or in individual portions. Add a wedge of lemon for extra flavor.
