Pork tenderloin with apples is a delicious and comforting dish that is perfect for fall. Season the pork tenderloin with salt, pepper, and thyme, then sear it in a hot skillet until it is browned on all sides. Transfer the pork to a baking dish and top it with sliced apples, onions, and a drizzle of maple syrup. Roast in the oven until the pork is cooked through and the apples are tender. Serve with roasted potatoes or a side of steamed vegetables.
