First add all 4 types of beans to pot. Then add the other veggies – onions, peppers, and garlic. Then add sweet potatoes. 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, and try to submerge 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, mix, and let sit for as long as you can, but at least 10 minutes.
