Place the raw chicken thighs or breasts in the Instant Pot insert in a single layer if possible.
Sprinkle the ground cumin and garlic powder evenly over the chicken.
Pour the 16 ounces of salsa verde over the chicken, covering as much as possible.
Secure the lid and set the pressure cooker to high pressure for 25 minutes (or use the Instant Pot poultry button if preferred).
When the cooking time is finished, perform a quick release of the pressure according to your cooker’s instructions.
Open the lid, shred the chicken directly in the pot using two forks or tongs, mixing it with the salsa verde.
Season with salt and black pepper to taste, then serve in tortillas, with rice, or use in burritos, quesadillas, tacos, or salads.
