In a large pot, heat about 2 tablespoons of olive oil. Add 3 cloves of chopped garlic and brown in the oil. Next add your chopped onion and cook until tender. Add the sliced carrots, sliced celery, canned tomatoes and cook about 5 minutes. Next add all of your seasonings to the vegetables and continue to cook about 5 minutes on medium. Add your two boxes of chicken stock and the cut up chicken. Turn heat on high just until boiling. Once soup comes to a good boil, lower the heat to medium. Cover with a top and cook about 30-45 minutes.
