Soak the bamboo skewers in water for about 1 hour (metal skewers can be substituted). Thread the skewers, alternating pork and red-onion cubes. Combine 1⁄2 cup of the oil, vinegar, sage, and garlic in a large casserole. Add the brochettes, turning to coat the meat on all sides. Cover, and marinate in the refrigerator for 1 hour.
Light the coals, or preheat the gas grill to medium-hot. Remove the brochettes from the marinade, shake off most of the sage leaves, and pat the brochettes dry. Brush the pork with the remaining olive oil, and season with salt and pepper.
Grill the brochettes, turning, until fully browned all over, about 8 to 10 minutes altogether. Brush with the tapenade (recipe below), and squeeze a few drops of fresh lemon juice over the pork.(Published 2003)
