Place chicken, rice, broth, tomatoes, taco seasoning, peppers, onion, garlic, oregano, cilantro, salt and pepper into Instant Pot. DON’T STIR.
Place lid on the Instant Pot and turn vent to the sealing position. Cook on manual high pressure (or the pressure cook button for newer models)for 5 minutes. When timer is up, allow for a 5 minute natural release and then manually release the remaining pressure.
Take chipotle peppers out and stir everything up. Add shredded cheese to the top and place lid back on. Allow it to sit for about 5 minutes (just enough time to allow the cheese to melt).
Top with sour cream, cilantro, or any of your other favorites and enjoy!
