Cook the whole wheat pasta according to package instructions. Drain and rinse under cold water to cool.
In a large mixing bowl, combine the cooled pasta, cherry tomatoes, cucumber, chickpeas, red bell pepper, feta cheese, and red onion.
In a small bowl, whisk together the olive oil, red wine vinegar, dried oregano, garlic powder, salt, and pepper.
Pour the dressing over the pasta salad and toss gently to combine all ingredients evenly.
Cover the salad and refrigerate for at least 30 minutes to allow the flavors to meld.
Before serving, give the salad a quick toss and garnish with fresh parsley.
