In a large stockpot, sauté the sausage over medium heat until brown. Add the onion, bell pepper, jalapeño and garlic. Sauté until onions are clear. Stir in the cumin, oregano, chili powder and coriander. Add the chicken stock and bring to a boil. Reduce heat to medium low and simmer for about 15 minutes.
Stir in the beans, corn and tomatoes. Bring back to a simmer and add salt and pepper taste. Turn heat to low and simmer about 30 minutes. Add chicken and simmer on low for 10 minutes.
Note: If you like your chili thicker, slowly stir in a tablespoon or so of masa flour before adding the chicken.
