Spray a soup pan with cooking spray and bring up to medium high heat. Add onions and cook for about 2 minutes. Add the sausage and cook for another two minutes. Add the bell pepper and garlic. Cook an additional 2 minutes.
Add the broth, cumin, and tomatoes. Bring to a boil. Reduce the heat to a simmer and add chipotle and beans. Cook covered for about 10 minutes.
Season to taste with salt and pepper.
Serve with a sprinkle of Cilantro or some fat free sour cream.
**Variation Idea: I have tried this as a smooth soup -- brown off the turkey in a separate pan, following all of the other directions up until the point the beans are added. I use a hand held blender to blend up the soup. Afterwards I add the turkey and some additional beans to give a little texture.
