Brush the cooking grates clean. Grill the chicken, smooth side down, over direct high heat, with the lid closed as much as possible, until no longer pink when pierced in the center with a small, sharp knife, 3 to 4 minutes. Turn over and grill just to sear the surface, about 1 minute. Transfer the chicken, with the first grilled sides facing up, to a serving platter or individual plates. Spoon the relish over each piece and squeeze fresh lemon juice on top just before serving.
