Place sliced vegetables in the bottom of the pot to help them release water when the meat is cooking.
In a bowl, mix together the pork with all the spices and the lemon juice.
Place pork on top of the onions and garlic.
Put 1/2 cup of water into your bowl and rinse it out to get the last of the spices, and pour this water onto the pork.
Set your Instant Pot to Meat setting, or high pressure for 35 minutes.
When it's done use natural release.
Remove the pork, take it out of the water which may be somewhat salty.
Leave the pot on Saute and reduce the remaining water/sauce in there while you finish the next steps.
Put the coconut oil in a hot cast iron pan. If you wanted, you could also fish out the pork fat that is cooked, and set that to render. I did both and it was yummy.
Lay the shredded meat in a flat layer and let it brown undisturbed.
When it's partially brown, stir it and keep cooking until it's crispy in parts.
Once it's well crisped, put in a little of the concentrated broth. Your skillet should be hot enough that most of it just dissolves, leaving behind the flavor. I used almost all of my broth, small portiojns at a time to flavor the meat.
Serve with guacamole, salsa, sour cream or low carb tortillas, or eat plain.
