Step by Step method

1. Step 1.

   Cut pork chops into 1 1/4-inch cubes. Combine 1/4 cup oil, garlic, soy sauce, 3/4 teaspoon salt, and 1/2 teaspoon pepper in medium bowl. Add pork cubes, toss to coat, and marinate for 15 minutes. Toss pineapple, peppers, and onion with remaining 2 tablespoons oil in medium bowl and season with salt and pepper.

2. Step 2.

   Thread pork, pineapple, peppers, and onion onto eight 12-inch metal skewers. Brush skewers with any remaining marinade.

   Grill kebabs over high heat, turning skewers, until pork is well browned and cooked through, 8 to 10 minutes. Serve.
