Pork tenderloin with mustard sauce is a flavorful and elegant dish that is perfect for a dinner party. 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, whisk together some Dijon mustard, chicken broth, and heavy cream. Cook the sauce until it thickens, then return the pork to the skillet and cook everything together until the pork is cooked through. This dish pairs well with roasted vegetables and a glass of red wine.
