In a deep pot over medium heat add oil, carrots, celery, onions and bay leaves. Season with salt and pepper. Cover pot and cook veggies 5 or 6 minutes. Combine meat, egg, garlic, cheese, bread crumbs, salt and pepper, nutmeg. Uncover your soup pot and add broth and water to the pot. Increase heat to high, bring soup to a boil. When soup boils, reduce heat a bit and start to roll meat mixture into small balls, dropping them straight into the pot. Add pasta and stir.
Cover and simmer soup 10 minutes. When pasta is tender stir in chopped spinach in batches.
Mitzi found this recipe in the Omaha World Herald about 10 years ago. She serves it as a Sunday evening supper because it's light, and so that she can have left overs for work.
