In your Instant Pot, add in the ingredients in this order: chicken, then directly on top: lime juice, taco seasoning, salsa, and cilantro.
Close the lid, set the valve to sealing, click the manual button, and cook on high pressure for 6 minutes.
When done, natural pressure release for 10 minutes before quick releasing whatever that’s left. If you’re in a rush, you can quick release after the 6 minutes.
Open the lid, shred the chicken, and toss to coat the chicken to ensure it’s coated with sauce. Squeeze a wedge of lime on top of each serving before serving.
