In a pot of salted boiling water, cook the orzo pasta according to package instructions until al dente. Drain and rinse under cold water to cool. Set aside.
In a small mixing bowl, whisk together the olive oil, lemon juice, dried oregano, salt, and pepper until well combined.
In a large mixing bowl, add the cooked orzo, shredded chicken, cherry tomatoes, cucumber, red bell pepper, red onion, Kalamata olives, feta cheese, and fresh parsley.
Pour the vinaigrette over the orzo mixture and gently toss to combine all ingredients evenly, ensuring the dressing coats everything.
Taste the salad and adjust seasoning with extra salt, pepper, or lemon juice if desired.
For the best flavor, cover the salad and refrigerate for at least 30 minutes before serving.
Notes
Serve in a large salad bowl or individual plates. Garnish with additional feta cheese and parsley.
