In a large pot of salted boiling water, cook the pasta according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.
In a small bowl, whisk together the olive oil, red wine vinegar, dried oregano, salt, and pepper until well combined.
In a large mixing bowl, add the cooked pasta, shredded chicken, cherry tomatoes, cucumber, red onion, olives, and feta cheese.
Pour the dressing over the pasta mixture and gently toss to combine, ensuring everything is evenly coated with the dressing.
Sprinkle chopped parsley over the salad for added freshness.
Cover the pasta salad with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld together.
Give the salad a gentle toss again before serving.
Notes
Serve the salad in a large serving bowl and garnish with additional feta and parsley for an appealing look.
