Bring a large pot of salted water to a boil. Cook 1 lb orzo according to package directions until al dente.
Drain the pasta and rinse thoroughly with cold water to stop the cooking process.
In a very large mixing bowl, combine the cooled pasta, 15 oz chickpeas, 1 pint cherry tomatoes, 1 diced zucchini, 1 diced red onion, 1/2 cup kalamata olives, 1 diced yellow bell pepper, and 13.5 oz artichoke hearts.
In a small separate bowl, whisk together 1/4 cup olive oil, 3 tbsp lemon juice, and 1 tsp dried oregano to create the dressing.
Pour the dressing over the vegetables and pasta, tossing well to coat all ingredients evenly.
Gently fold in 1 cup crumbled feta cheese and 1/4 cup fresh parsley just before serving.
