In a large cast-iron skillet, heat the oil over medium-high heat. Add the pork pieces and the seasoning and cook for 7 to 9 minutes, until the pork is cooked through and no longer pink.
Add half of the pineapple to the skillet. Continue cooking for about 2 minutes, until the pineapple has released its juices and become incorporated with the pork into a sauce. Remove the pan from the heat.
Assemble the tacos:
To assemble the tacos, place a layer of cooked pork on each tortilla and top with some pineapple salsa and crumbled cheese.
