Press the sauté function button on your Instant Pot and let the pot get warm. Add olive oil, then add the ground turkey. Let the ground turkey simmer for about two minutes, stirring occasionally, just to lightly brown it.
Turn the sauté function off. Add the taco seasoning, the salsa, and the green chilies (liquid from can included). Give everything a good stir to evenly distribute seasoning.
Place the lid on the Instant Pot and make sure it's locked into place. Ensure that the valve is pointing towards "sealing". Finally, cook everything for 8 minutes on high pressure.
While the turkey cooks, prep your toppings and set them aside.
When the Instant Pot beeps, indicating that it's done, carefully move the valve to *venting* for a quick release. Be cautious as hot steam will spit out of the valve. Once all of the steam escapes, open the lid and give everything a stir.
Serve on tacos with your favorite toppings!
