How to Make It
Light a grill. In a skillet, toast the pine nuts over high heat, stirring, until golden, about 4 minutes. Transfer to a bowl.
Brush the chops with oil and season with salt and pepper. Grill the chops over high heat, turning once, until cooked through, 10 to 11 minutes. Transfer to a plate; let rest for 5 minutes.
Meanwhile, brush the nectarines with olive oil and grill cut side down until browned, about 3 minutes. Turn and grill until charred and softened, about 2 minutes longer; cut into 1/2-inch dice. Put the nectarines in a bowl and stir in the vinegar and honey. Add the onion, basil and pine nuts and season with salt and pepper. Serve the pork chops topped with the relish.
