FAQs
Can I make this in an Instant Pot?

Is this soup spicy?
It has a mild to medium heat from the green chilies. You can adjust the spices to suit your personal taste easily.
Can I use frozen chicken?
It is safer to thaw the chicken before slow cooking it. This ensures it cooks evenly and stays out of the danger zone.
