Add the chicken thighs, salt, salsa, and water to the bowl of an instant pot. Stir to coat the chicken.
Seal the instant pot and cook on high pressure for 10 minutes. Allow the pressure to naturally release for 10 minutes before manually releasing any remaining pressure.
Transfer the chicken to a cutting board and shred it with a fork.
Notes
If you do not have an Instant Pot: Preheat the oven to 425°F and line a baking sheet with parchment paper. Rub the chicken with kosher salt, salsa, and a tablespoon or so of olive oil (leave the water out). Bake for 25 minutes. Transfer the chicken to a cutting board and shred it with a fork.
