Vegetable Soup

Add all ingredients, except spinach and olive oil, to the slow cooker. Cover and cook on low 6-8 hours, or until the vegetables are tender. Add spinach, stir and continue cooking just until wilted, approximately 5 minutes. Optional: When serving, drizzle a little olive oil over each bowl of soup - 1/2 tsp per bowl.

Note: If you prefer a thicker soup, after 5 hours of cooking, remove 1 cup of soup along with ingredients and mash with a fork. Return to the slow cooker, stir and continue cooking 1-3 hours.
