In this easy one-pan dinner, boneless pork loin roast is cooked over a bed of carrots and parsnips for an all-in-one dish that makes an impressive centerpiece for a holiday meal or Sunday dinner. Choose free-range heritage pork if you can—its flavor really shines with no more seasoning than a bit of thyme and a little sea salt. If you'd like, dress up the meal with a traditional Irish apple condiment—Ploughmans chutney or Bramley applesauce, which you can find in specialty stores and online.
