Heat olive oil in large soup pot over medium heat. Add carrots, onion, and celery and saute for 10 minutes or until softened, stirring occasionally. Stir in garlic and saute another minute. Add broth, water, tomatoes, and spices. Stir, increase heat, and bring to a boil. Stir again, reduce heat to medium-low and simmer for 20 minutes.
Remove bay leaf, stir in tortellini, chicken, lemon juice, and spinach, and continue to simmer another 10-12 minutes until spinach is wilted and chicken & tortellini are heated through.

If you lack leftover cooked chicken or are looking for a Meatless Monday recipe, you could also easily make this into a vegetarian soup recipe by using vegetable rather than chicken broth and substituting a can of Great Northern or Cannellini beans for the chicken; just add in the beans when you add the broth and tomatoes, rather than during the last ten minutes of cook time.
