First add all 3 types of beans to pot. Then add the other veggies – onions, peppers, and garlic. Next add the spices – chili powder, cumin, oregano, bay leaf, and salt. Now, add your liquid components – chicken broth and tomato sauce. Give a good mix.
Finally, add chicken breasts, making sure they are submerged in the liquid.
Lock lid and cook for 15 minutes at high pressure. Once cook time is complete, quick-release pressure and remove lid.
Remove chicken breasts and transfer them to a large mixing bowl. Using 2 forks, shred chicken into bite-size pieces. Return chicken to pot and let sit for as long as you can, but at least 10 minutes.
Serve with your favorite toppings, or none at all. And, of course, some cornbread!
