Set your Instant Pot to "Sauté" mode and add the olive oil. Cook the onion and bell pepper for 3-4 minutes until softened, then add the garlic and cook for another minute.
Add the chicken breasts, diced tomatoes, black beans, corn, chicken broth, chili powder, cumin, paprika, salt, and pepper. Stir to combine.
Close the lid, set the valve to "Sealing," and cook on high pressure for 10 minutes.
When the timer goes off, let the pressure naturally release for 5 minutes, then do a quick release for any remaining pressure.
Remove the chicken breasts and shred them using two forks. Return the shredded chicken to the pot.
Stir in the lime juice and taste for seasoning, adding more salt if needed.
Serve hot with crushed tortilla chips, sliced avocado, shredded cheese, sour cream, and fresh cilantro. Let everyone build their perfect bowl!
