Make the sauce in a large measuring cup by combining ½ cup low sodium soy sauce, ¼ cup ketchup, ¼ cup light brown sugar, and the juice from 1 (15-ounce) can pineapple slices in juice, reserving the pineapple slices for later. Set aside.
Heat 1 tablespoon of the 2 tablespoons vegetable oil in a large skillet over medium-high heat.
Season 1 ½ pounds thin pork chops on both sides with salt and ground black pepper. Add the pork to the skillet and cook for about 2 minutes on each side until each side is browned. Remove from the pan and set aside.
Add the remaining tablespoon of oil to the skillet. Add 1 tablespoon minced garlic and 1 teaspoon fresh minced ginger and cook for 1 minute, stirring constantly.
Pour the sauce into the skillet. Bring to a simmer and cook for 2-3 minutes.
In a small bowl combine 1 teaspoon cornstarch and 1 tablespoon water, then stir the cornstarch mixture into the sauce. Add the pork back to the skillet.
Add the reserved pineapple slices and simmer for 10 minutes until the sauce has thickened and the pork reaches an internal temperature of 145 degrees Fahrenheit.
Serve immediately with chopped parsley for garnish, if desired.
