In a medium bowl, whisk together the pineapple juice, soy sauce, brown sugar, ginger, vegetable oil, gochujang and garlic. Pour into a large resealable plastic bag and add the pork, moving the bag around to ensure the marinade coats all of the pork. Seal the bag and refrigerate for 1 1/2 hours.
After 1 1/2 hours, remove the bag with the meat from the refrigerator and let sit at room temperature for 30 minutes. If using wooden skewers, soak in water at this point.
Heat a grill or grill pan to medium-high heat.
Remove the pork from the marinade and discard the marinade. Thread 5 to 6 pork cubes on each skewer. Season the pork on all sides with a pinch of salt and a few grinds of black pepper. Grill and flip to cook on all sides until cooked through, 2 to 3 minutes on each side. Serve immediately with Sunny's Baked Pineapple Rice (or cover with aluminum foil until serving).
Sunny's Baked Pineapple Rice:
Preheat the oven to 350 degrees F.
Put the rice and pineapple in an 8-by-8-inch baking dish. In a medium pot on high heat, add the coconut milk, butter, salt, some black pepper and 1 cup water. Cook until the butter melts and the mixture is just below simmering. Pour over the rice and immediately cover tightly with aluminum foil. Bake until the rice is tender and the water is absorbed, 35 to 40 minutes.
Add the almonds and scallions, fluff with a fork and serve warm.
