Step 1In a small saucepot, cook the onion in the oil over medium-low heat until translucent. Add the garlic and cook until aromatic, about 1 more minute. Stir in the bell pepper, flour, salt, chili powder and cumin and continue to cook until the spices are aromatic, about 1 minute. Add the tomatoes, broth, beans, jalapeño, cilantro and green chile. Bring to a boil, then reduce heat and simmer, covered, for 20 minutes, stirring occasionally. Finally, add the chicken and continue to simmer, covered, until the chili is nicely thickened, about 20 minutes.
