Bring a large pot of salted water to a boil and cook the chickpea pasta according to package directions.
Drain the pasta and rinse with cold water to stop the cooking process and prevent sticking.
In a small mixing bowl, whisk together Greek yogurt, lemon juice, dried oregano, garlic powder, salt, and pepper to create the dressing.
In a large mixing bowl, combine the chilled pasta, cubed chicken, edamame, cherry tomatoes, baby spinach, and red onion.
Pour the dressing over the salad ingredients and toss thoroughly until evenly coated.
Fold in the crumbled feta cheese.
Refrigerate for at least 30 minutes before serving to allow flavors to meld.
