These pork and pineapple skewers are a delicious and tropical twist on traditional kebabs. Cubes of pork are marinated in a sweet and tangy marinade made with pineapple juice, soy sauce, garlic, and brown sugar. Thread the pork onto skewers along with pineapple chunks and grill or broil until the pork is cooked through and the pineapple is caramelized. Serve these flavorful skewers with rice or a salad for a complete meal.
