Pork tenderloin with apples and onions is a classic combination that is both sweet and savory. To make this dish, season the pork tenderloin with salt, pepper, and your favorite herbs and spices. Then, sear the pork in a hot skillet until it is browned on all sides. Remove the pork from the skillet and set it aside. In the same skillet, sauté sliced apples and onions until they are tender and caramelized. Return the pork to the skillet and cook everything together until the pork is cooked through. This dish is perfect for a cozy fall dinner.
