Slather both sides of each pork chop with the mole paste and season generously with salt and pepper. Let marinate at least 30 minutes or up to overnight.

Heat a charcoal or gas grill to medium-high heat. Brush the grates with oil and grill the pork chops until browned one one side, about 4-5 minutes. Flip and continue cooking another 3-4 minutes on the other side.
