Prep your veggies. Dice the pineapple, red onion, and jalapeno.
Trim the fat off the chicken thighs and place in the Instant Pot.
Put the diced veggies, sriracha, mustard, lime juice, chili powder, cumin, red pepper flakes, garlic, and salt in the pot and stir it all together.
Put the lid on the Instant Pot in the sealing position.
Hit the manual pressure cook button and cook for 20 minutes (25 min if your chicken is frozen).
Once the timer goes off, release the steam valve. Take the chicken out and chop or shred it.
Strain the juice out of the instant pot through a strainer. Leave some juice in the pot for flavor. (see video)
Put everything back in the pot and stir. Serve with tortillas filled with sour cream, sriracha, lettuce and the chicken mixture. I just heat the tortillas on a pan. A must for any taco! It makes a huge difference.
Enjoy!
