Add ground turkey to a medium soup pot or dutch oven. Break up into small pieces. Add the onion and cook over medium high heat until turkey is almost cooked through and onion is almost translucent (about 5-7 minutes). Drain fat if needed.
Add the spices to the turkey and onion mixture; stir.
Add diced green chilies, crushed tomatoes, beans with their liquid, corn, and chicken stock. Stir.
Cover and bring mixture to a boil.
Cook, stirring often, with pot partially covered, until mixture thickens and flavors meld, about 15-20 minutes (longer if desired).
Add additional salt, pepper and/or cayenne as desired.
Serve hot with chopped onions and cheddar cheese.
