For the pork: Put the trimmed tenderloins into a baking dish, and pour over half of the marinade, turning to coat. Cover the dish with plastic wrap, then place the pork in the refrigerator, and let it marinate for a minimum of 30 minutes to a maximum of 24 hours.
Preheat the oven to 400 degrees F.
Heat the vegetable oil in a large, ovenproof saute pan over medium-high heat. Remove the pork tenderloins from the marinade and sear on all sides in the hot pan. Baste the pork with the remaining marinade throughout the cooking process.
Slide the pan into the preheated oven, and cook until the pork is cooked through, approximately 20 minutes. Allow the meat to rest for 15 minutes before serving.
