Boil chickpea pasta in salted water for 7-9 minutes or until al dente.
Drain the pasta and rinse under cold water to stop the cooking process and remove excess starch.
In a small whisking bowl, emulsify olive oil, lemon juice, dried oregano, salt, and pepper to create the dressing.
In a large mixing bowl, combine the chilled pasta, diced chicken, chickpeas, tomatoes, cucumber, and red onion.
Fold in the crumbled feta cheese.
Drizzle the dressing over the salad and toss thoroughly to ensure even distribution.
Refrigerate for a minimum of 30 minutes to allow flavors to meld before serving.
