Add all of the ingredients, except lime juice and cilantro, to the liner of the instant pot. Mix well. Place the lid, make sure it is set to sealing. Cook high pressure for 35 minutes. After the timer goes off, let the pressure release naturally.
After the pressure releases, remove the lid and use a slotted spoon to remove the meat from the liquid and onto a 13x9 rimmed baking sheet. Pre-heat your broiler.
Using 2 forks or tongs, shred the meat and remove any large chunks of fat. Place the meat under the broiler and let the meat get brown and crispy, about 5-8 minutes. Watch closely so they do not burn.
