In a heavy bottom dutch pot or similar over high heat, add chicken breasts, broth, spices (cumin, coriander, paprika, chipotle, red chili) salt, and pepper. Bring to a boil, reduce the heat to low, and simmer for 30 minutes.
Meanwhile, saute red bell peppers until softened, add onions, garlic and saute for a couple of minutes more. Set aside.
Remove the chicken from the pot and shred it finely, return to the pot.
Mash one-half of the beans until paste-like, add it to the pot along with the rest of the beans, corn, bell peppers, onion, garlic, salsa. Stir to combine and simmer for 20-25 minutes.
After that, mix cornstarch with water and carefully stir in the chili. Simmer the chicken chili until it is thickened. About 2-3 minutes. Make sure the heat is on low.
Enjoy warm with a dollop of sour cream, fresh cilantro, lime wedges, tortilla chips, and more chipotle or red chili powder on top.
