Pat pork chops dry with paper towels. Season lightly with salt and pepper on both sides.
Heat olive oil and butter in a large skillet over medium-high heat. Add pork chops and sear for about 3–4 minutes per side until golden brown. Remove from skillet and set aside.
In the same skillet, reduce heat to medium. Add minced garlic and ginger; sauté for 30 seconds until fragrant.
Stir in pineapple chunks, pineapple juice, soy sauce, brown sugar, and vinegar. Simmer for 2–3 minutes.
Mix cornstarch and water in a small bowl. Add to the pan and stir until sauce slightly thickens.
Return pork chops to the skillet, spoon sauce over them, and simmer for 8–10 minutes, or until pork reaches an internal temperature of 145°F (63°C).
Garnish with chopped green onions or parsley and extra pineapple sauce. Serve with rice, steamed vegetables, or mashed potatoes.
