Once the chicken is done, take it out and shred it with a fork.
Add the remaining ingredients to the Instant Pot or dutch oven and add the chicken back into the pot.

Let the soup sit for as long as possible. I like to put mine on during nap time and let it sit until dinner.
Top with cilantro, green onions, cheese, tortilla chips, cour cream, taco sauce, avocado....the options are endless!
