1. Saute onions and celery in butter over medium heat until soft.
2. If using raw chicken, add now and cook through. Otherwise, add your cooked chicken, bone broth, 2 cans of beans, and next five ingredients. Cook on medium-low for one hour, stirring frequently.
3. Process the final can of beans in a blender with a small amount of cooking liquid. Stir puree into chili. Stir in cilantro just before serving. Top with cheese, crème fraîche and/or salsa as desired.
