Season the pork with the garlic powder.
Heat the oil in a 10-inch skillet over medium-high heat. Add the pork and cook until it's well browned on both sides.
Add the onion, soup, water, pineapple with juice, soy sauce and honey to the skillet and heat to a boil. Reduce the heat to low. Cook for 10 minutes or until the pork is cooked through.
Serve the pork with the rice and sprinkle with the green onions.
