Set your Instant Pot to saute mode and cook the bacon in it. Once crisp, remove from the pot and set aside, then drain all but one tablespoon of drippings from the pot.
Add the onion and garlic and sauté for 4 to 5 minutes, until the onion is translucent.
Add the green chilis and cook for 1 minute, until fragrant, then add the seasonings and stir to combine. Pour in the chicken broth and add in the chicken, beans, and corn.
Using the manual setting, place the lid on pot, making sure the valve is sealed, then set it to cook for 15 minutes. Once the 15 minutes is up, turn the valve to “venting” to manually release the remaining pressure.
Remove the chicken from the pot and shred it with two forks, then return it to the pot and stir in the sour cream, lime juice, and bacon.
Garnish each serving with avocado slices, cilantro, sour cream, and a lime wedge and enjoy!
