Heat the oil in a 10-inch skillet over medium-high heat. Add the pork and cook until well browned on both sides.
Stir the onion, soup, water, pineapple with juice, soy sauce and honey in 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 and sauce with the rice and sprinkle with the green onion.
