Add olive oil to a dutch oven or large pot. Heat on medium heat, add onions. Cook for 3-5 minutes until slightly softened, stirring occasionally.
Add garlic, saute for one minute.
Add chicken, chicken broth, green chilies, cumin, oregano, and cayenne. Reduce heat to low and allow to simmer.
Using a potato masher, mash 1/2 of can of white chili beans until it resembles a chunky paste. Add the paste and remaining can of beans and pinto beans to the pot.
Partially cover and allow to simmer for 10 minutes, stirring occasionally. The bean paste will help thicken it up.
Top with cheese and cilantro as desired.
Add optional sour cream, jalapeno, and avocado
Notes
This is great leftover and it also freezes well. Perfect for meal prepping!Use either a potato masher or a food processor for some of the beans to give it a creamier base. If using a food processor add a little broth to it.
