Cook the orzo: Bring a pot of salted water to a boil, add the orzo, and cook according to package directions until al dente. Drain, then rinse and drain a few times with cold water until the pasta is cool.
Prepare the salad ingredients: In a large mixing bowl, combine the cherry tomatoes, cucumber, pepper, olives, red onion, feta cheese, chickpeas, oregano, orzo and fresh parsley.
Make the dressing: In a small bowl or jar, whisk together the olive oil, red wine vinegar, salt, and pepper until well combined.
Combine if serving immediately (see note for meal prep*): pour the dressing over the salad, and gently toss to coat.
Serve immediately and enjoy as a main or side dish.
