What else shall I put in my turkey vegetable soup?

At last the turkey from Thanksgiving has succumbed and the carcass is in the stock put right now with bay leaf. dried thyme, onion, carrot and celery with leaves.

Destination: Turkey Vegetable Soup. Besides the aforenamed onions, carrots, and celery (well, not the same ones, but different ones), what else should I put in?

I was contemplating green beans and canned tomatoes. Any other ideas? (Note: no starches like potatoes, rice, macaroni.)
