Heat butter in a medium skillet over medium heat until melted. Add mushrooms and onion. Sauté 2 minutes. Remove from heat, then add spinach, bread crumbs, salt, pepper and 1-1⁄2 tsp. of the ginger.
Slit each chop horizontally from the outside edge in; stuff each chop with the veggie mixture and then sprinkle the outside with salt and pepper to taste.
Heat 1 tsp. oil in a large skillet over medium-high heat. Brown chops two minutes on each side. Transfer to a baking dish and bake uncovered for 30 minutes. Remove from oven.
Blend remaining 1-1⁄2 tsp. ginger with orange marmalade and brush on top of pork chops. Return pork chops to oven and bake additional 5–10 minutes.
