In a bowl combine the pineapple, red onion, cilantro, lime juice and 1/2 teaspoon of salt and set aside.
In a non-stick skillet over medium heat add the ground pork and cook until no longer pink, breaking up the ground meat with a spatula or wooden spoon.
Into the cooked pork stir the orange juice, chipotle sauce, smoked paprika, cumin, garlic powder, remaining one teaspoon of salt and cayenne pepper. Stir well and allow to simmer for about 5 minutes.
Serve the ground pork taco meat with tortillas, the fresh pineapple salsa and shredded Pepper Jack cheese.
