In a mixing bowl combine the teriyaki sauce, soy sauce, brown sugar, garlic, ginger, green onion, and pepper. Mix and add the pork chops coating them in the marinade. Cover and refrigerate for an hour.
Preheat the oven to 375°F, 190°C or gas mark 5.
Place the pork chops on the sheet pan, cook for 20-25 minutes or until the internal temperature reaches 145°F or 63°C.
Make a glaze (optional)
In a saucepan over medium high heat bring the marinade to a boil and let the sauce reduce by half. Serve this over the pork chop.
