  • Cook the Chicken: Turn your Instant Pot onto the sauté setting and add 1 tbsp of the olive oil. Once heated, add the chicken. Cook for 3-4 minutes until the chicken begins to brown. Remove the chicken from the pot and set aside.
  • Add Ingredients: Add the remaining olive oil to the pot along with the onion and bell peppers. Cook for 2-3 minutes, then add the garlic. Stir and cook for 30 seconds, or until aromatic.

  • Cook: Secure the Instant Pot lid and make sure the knob is set to SEAL. Cook for 4 minutes on high pressure.
  • Finish: Quick release the pressure by turning the knob on the lid from SEAL to VENT. Stir in the sour cream and cheese. Taste for seasoning and add salt and pepper as needed.
  • Garnish and Serve: Garnish with cilantro and serve.
