This boneless pork chop recipe is a delicious and healthy option for dinner. To make the mushroom sauce, sauté sliced mushrooms and onions in a skillet until they are tender. Then, add chicken broth, Dijon mustard, and thyme. Season the pork chops with salt and pepper and cook them in a separate skillet until they are browned on both sides. Then, pour the mushroom sauce over the pork chops and let them simmer until the sauce has thickened.
