Preheat oven to 400 degrees F. Lightly oil a baking sheet or coat with nonstick spray.
Melt butter in a large skillet over medium high heat.
Rub both sides of the pork chops with sage; season with salt and pepper, to taste. Add to the skillet and sear both sides until golden brown, about 2-3 minutes.
Place pork chops and green beans in a single layer onto the prepared baking sheet. Drizzle green beans with olive oil and sprinkle with garlic; season with salt and pepper, to taste.
Place into oven and roast until the pork is completely cooked through, reaching an internal temperature of 140 degrees F, about 12-15 minutes.
Return skillet to medium high heat and melt butter. Add apples, brown sugar, cinnamon and nutmeg. Cook, stirring occasionally, until apples just begin to soften, about 3-4 minutes. Stir in maple syrup, stirring occasionally, until the sauce thickens, about 5 minutes.
Serve pork chops immediately, topped with apple mixture, garnished with parsley, if desired.
