SOAK the pitted dates in the hot water. Set aside.
COMBINE the chili powder, garlic powder, onion powder, cumin, paprika, and salt in a small bowl. Rub the seasonings onto the pork roast.
BLEND the soaked dates and water in a food processor or blender until smooth, with no large chunks.
PLACE seasoned roast on the bottom of the crockpot, Instant Pot, or into a 9x13 pan. Pour half of the date mixture (1 cup) on top of the roast, reserving the other half.
COOK until roast shreds easily as follows:
CROCKPOT: Cover with lid and cook on low for 6 hours or 4 hours on high.INSTANT POT: Seal with lid and cook on manual on high pressure for 1 hour. Let the Instant Pot natural release (don’t touch release knob) for 20 minutes. OVEN: Preheat oven to 325. Cover the pan with foil. Bake for 4-5 hours. DISCARD the liquid in the crockpot, instant pot or 9x13 pan. Shred roast with two forks, pulling in opposite directions.
COMBINE reserved 1 cup date mixture, salsa, and garlic salt. In a saucepan on the stove, combine this liquid with the shredded pork. Simmer for 20 minutes, uncovered. This can also be done on Saute in your Instant Pot.
