Prepare the Marinade: In a small bowl, mix together smoked paprika, garlic powder, onion powder, salt, and black pepper. Rub the pork chops with olive oil and coat them evenly with the spice mixture.
Marinate the Chops: Let the pork chops sit at room temperature for about 30 minutes to absorb the flavors.
Make the Pineapple Salsa: In a separate bowl, combine diced pineapple, red onion, cilantro, lime juice, and jalapeño (if using). Toss well and set aside to let the flavors meld.
Preheat the Grill: Preheat your grill to medium-high heat.
Grill the Pork Chops: Place the marinated pork chops on the grill and cook for about 6-7 minutes on each side, or until the internal temperature reaches 145°F (63°C). Remove from the grill and let them rest for a few minutes.
Serve: Top the grilled pork chops with the fresh pineapple salsa and enjoy with your favorite sides.
