3 pounds boneless pork loin, cut into 1 inch cubes
1 cup onions, thinly sliced
1/4 cup soy sauce
1/4 cup lime juice
1 tablespoon brown sugar
1 tablespoon ground coriander
1 tablespoon cumin seeds
1 teaspoon salt
1/2 teaspoon pepper
1/2 teaspoon ginger

Place pork cubes in a shallow baking dish. Combine other ingredients and mix well. Pour over pork, cover and let marinade for at least 4 hours. Drain and reserve marinade. Arrange pork cubes onto skewers, leaving about 1/4 inch space in between each cube. Brush marinade over meat and place on a hot grill. Cook for about 5 minutes over a medium fire then turn. Baste with more marinade and continue cooking for another 5 minutes. Continue cooking and turning until done.
