1. Sprinkle chops on both sides with salt. Warm oil in a large skillet over medium-high heat. Add chops and sear on 1 side until well browned, 3 to 4 minutes. Reduce heat to medium, turn chops and continue to cook until an instant-read thermometer inserted into center of chops reads 140ºF to 145ºF, 4 to 6 minutes longer. Transfer to a platter and cover with foil to keep warm.
2. Add pineapple and 2 Tbsp. water to skillet. Cook, stirring to incorporate browned bits on bottom of skillet, until warmed through, about 2 minutes. Stir in mint and red pepper. Spoon over chops and serve.
