In small bowl, combine chili powder, cinnamon, oregano, cumin, paprika, and salt. Add to onion and garlic in pot, then add diced roasted peppers and cooked bison. Stir through. Add tomatoes, half filling the empty can with water to rinse out any remaining tomato sauce, and add directly to pot. Add pinto beans and black beans with cacao powder and simmer on medium-low heat for approximately 40 minutes, until the tomatoes have broken up. Serve with chopped cilantro and crumbled goat cheese (if desired).
