Drain the pineapple chunks and reserve the juice.
Mix the reserved pineapple juice with the water, cornstarch, honey, soy sauce, brown sugar, ginger, and garlic in a small bowl until well combined. Set aside.
In a large, heavy saucepan or skillet, add the oil. Heat over medium-high heat for about 1 minute. Add onion and red peppers and saute for 3 minutes, constantly stirring, until they are vibrant in color and just tender. Remove the saucepan and reserve.
Add pork meat to the same saucepan and saute until no longer pink. Add pineapple chunks and oregano. Season with salt and black pepper to taste; mix to combine. Add the sauce.
Bring to a boil, then lower the heat to medium-low and simmer, uncovered, for 10 -12 minutes, occasionally stirring, until the pork is cooked. NOTE: The cooking time might be less or more depending on the size of your meat cubes. To check doneness, take one piece of pork, and poke a hole in it with a knife or fork, If the juices run clear or are very faintly pink, the pork is done cooking
Add the reserved onions and red peppers to the saucepan and toss to coat. Taste and adjust seasoning adding more salt and black pepper, if necessary.
Garnish with fresh chopped parsley, if desired. Serve immediately over rice or steamed vegetables.
