Season pork chops with 3/4 teaspoon salt and black pepper, to taste. Heat grill or grill pan to medium-high heat. Grill pork chops until browned, about 5 minutes. Flip and cook 5-6 minutes until food thermometer inserted in center registers 135 F. Transfer to plate and rest at least 5 minutes until internal temperature rises to 145-160 F. Gently stir peaches, pecans, onion, basil, jalapeno, lime juice and remaining salt. Add salsa on top of each pork chop with remaining salsa on side.
