In a large mixing bowl, combine the cooked pasta, cherry tomatoes, cucumber, red bell pepper, red onion, and olives.
In a small bowl, whisk together Greek yogurt, olive oil, lemon juice, garlic powder, and dried oregano to make the dressing.
Pour the dressing over the pasta and vegetable mixture and toss to combine.
Top the salad with crumbled feta cheese and mix gently to incorporate.
Refrigerate for 10-15 minutes before serving to allow the flavors to meld together.
