How to Make It
Combine broth, chicken, onion, carrots, celery, wine, and salt in a 6-quart slow cooker. Cover and cook on LOW until vegetables are tender, about 4 hours.
Increase heat to HIGH, and stir in orzo. Cover and cook until orzo is tender, 15 to 20 minutes. Stir in peas, parsley, zest, and juice.
