Ingredients

For marinade and pork:
2 tablespoons red wine vinegar
1 tablespoon dark sesame oil
2 garlic cloves, minced
2 teaspoons crushed red-pepper flakes
1/2 teaspoon salt
1 pound pork tenderloin, cut into 32 1-inch chunks

For sauce:
1/4 cup ketchup
2 tablespoons red wine vinegar
2 tablespoons sugar
2 teaspoons reduced-sodium soy sauce
1/4 teaspoon dark sesame oil

For kebabs:
2 red or green bell peppers, cut into 32 1-inch pieces
20-ounce can pineapple chunks

Directions

To make the marinade and pork: In a large bowl, combine the vinegar, oil, garlic, red-pepper flakes and salt. Stir in the pork, cover and chill for at least 6 hours or overnight. Drain the pork, reserving the marinade.

To make the sauce: In a small bowl, combine the ketchup, vinegar, sugar, soy sauce and oil. Set aside.

To assemble the kebabs: Soak eight 10-inch long bamboo skewers in water for 30 minutes (see note). Thread a bell pepper chunk followed by a pineapple chunk and a pork chunk onto a skewer. Repeat this sequence four times on each skewer.

Coat a grill rack or broiler pan with nonstick spray. Preheat the grill or broiler. Baste the kebabs with some of the reserved marinade. Grill over medium-hot coals or broil them on a rack for 20 minutes, or until the pork is no longer pink but still juice. Turn the kebabs 3 or 4 times during cooking. Drizzle with the marinade several times during the first 10 minutes of cooking. Discard any remaining marinade; do not serve it with the kebabs.

Just before removing the kebabs from the grill, spoon half of the sweet-and-sour sauce over them. Turn the kebabs, spoon the remaining sauce over them, and grill for 1 minute longer. Serve immediately. Makes 8 kebabs, 4 servings.

Note: Tribole says she soaks bamboo skewers in water before making kebabs so that the skewers don't burn during grilling. If you don't have bamboo skewers, use metal ones and skip the soaking time.
