In a 6-quart Dutch oven, brown and crumble chorizo.
Once chorizo is finished cooking, add onion and bell pepper. Season with salt and black pepper and cook for 3-4 minutes.
Add garlic, spices, chilies, tomatoes and broth. Stir to combine.
Add chicken to your soup. Bring to a boil and reduce heat to medium. Cook for 1 hour. After an hour, remove chicken from pot, shred and return to pot.
Serve soup with sliced avocado, Colby jack cheese and sour cream.
