This is my favorite soup of all time, not to mention the easiest I've ever made! I've made it in a slow-cooker putting all the ingredients in with frozen chicken breasts and added spinach right before serving. Turned out great!
- In a large saucepan bring broth and salsa to a boil.
- Add beans and chicken, heat through.
- Stir in spinach, cook just until wilted.
- Top with cheese if desired.
