Place the raw chicken thighs or breasts in the Instant Pot insert in a single layer.
Sprinkle the ground cumin and garlic powder evenly over the chicken, then pour the salsa verde on top, covering the chicken.
Secure the lid and set the pressure valve to sealing. Cook on high pressure for 25 minutes (or use the poultry button on an Instant Pot).
When the cook time ends, perform a quick release of the pressure according to your cooker’s instructions, then carefully remove the lid.
Use two forks to shred the chicken directly in the pot, mixing it with the salsa mixture.
Taste and season with salt and black pepper as desired, then serve warm in tortillas, over rice, or in your favorite dishes.
