Preheat oven to 425ºF.
Trim the silverskin from the pork tenderloins. Place pork in a resealable plastic bag. Pour Dale's seasoning and Worcestershire sauce over the pork. Let the pork marinate in the refrigerator for at least 30 minutes.
Remove the pork from the marinade and pat dry with paper towels. Season tenderloins with Montreal Steak Seasoning.
Heat olive oil in a large cast iron skillet over medium-high heat. Sear the pork for two minutes on all sides.
Place the skillet in the oven and cook for 15 to 20 minutes, until it reaches an internal temperature of 145ºF on a meat thermometer.
Let the pork rest for about five minutes before cutting into slices. Garnish with parsley.
