Remove the pork tenderloins from the fridge about half an hour beforehand and, in the meantime, preheat the oven to 180 degrees Celsius / 355 Fahrenheit top and bottom heat.
Pat the tenderloins dry with kitchen paper and sprinkle generously with salt and pepper to taste.
Heat a little oil and butter in a large frying pan and fry the meat on all sides. It does not need to be cooked, just seared.
Remove the tenderloins from the pan, wrap it in bacon or ham and place it in an oven dish.
Put the pork loin in the oven for about 15-20 minutes, depending on how thick/large your pieces of pork loin are. To ensure a juicy loin, maintain an internal temperature of 60-63 degrees. You can use a meat thermometer to check.
Remove the pork tenderloin from the oven and cover with aluminium foil before carving, this will allow the meat to rest for 5 minutes maintaining all its juices and give you a super tender piece of meat. Serve on a nice platter and enjoy!
