Veggie Tortellini Soup

This is a super low calorie (155  calories per 1 C.) soup that is packed with veggies.  This will be a great lunch soup.  I may get some of the fancy tortellinis they have at the Poot.  Chicken broth can be swapped in for vegetable broth...it may boost the calories a bit.

3 medium carrots, chopped
1 large onion, chopped
1 tbsp. olive oil
4 garlic cloves, minced
2 14.5oz. cans vegetable broth
2 medium zucchini, chopped
4 plum tomatoes, chopped
2 C. refrigerated cheese tortellini
1/3 C. chopped fresh spinach
1 tsp. minced fresh rosemary or 1/4 tsp. crushed, dried rosemary
1/4 tsp. pepper
1 tbsp. red wine vinegar

In a Dutch oven, saute carrots and onion in oil until the onion is tender.  Add the garlic, cook 1 minute longer. 

Stir in the broth, zucchini, tomatoes, tortellini, spinach, rosemary and pepper.  Bring to a boil.  Reduce heat; cover and simmer for 8-10 minutes or until tortellini are tender.  Just before serving, add in the vinegar.
