Kitchen Tips
- Use a sharp knife to butterfly the pork tenderloin. This will make it cook quickly and evenly. If this is your first time doing this, follow these steps:
Place the tenderloin on a plastic wrap or cutting board. Make a slit by cutting lengthwise down the middle. Be careful not to cut all the way through. The best results are achieved by cutting 2/3 of the way through, leaving 1/3 of the overall thickness at the long side of the tenderloin. Open the tenderloin like a book. Cover it with a second sheet of plastic wrap and pound it out to an even thickness with the flat side of a meat mallet or a rolling pin. 
Prep time: 15 minutes

How To Make Easy Apple and Walnut Stuffed Pork Tenderloin
#1. Preheat the oven to 350°F. #2. Soak the 6-8 toothpicks in a bowl of water. This is to prevent the toothpicks from burning in the oven. #3. Heat a tablespoon of olive oil in a large, heavy skillet on medium heat. Add in the onion and apple slices. Cook, stirring occasionally,y until the onions become slightly soft and translucent. Do this for around 3-4 minutes. #4. Remove from heat and add walnuts, breadcrumbs, and fresh thyme. Season generously with salt and pepper to taste. Set aside. #5. Lay the pork tenderloin flat and cover it with plastic wrap. Pound the meat with a meat mallet until around 1/2 inch thick. #6. Spread the diced apples and walnut mixture over the meat and tightly roll the tenderloin like a jelly roll. Secure the walnut and apple stuffing inside the tenderloin with toothpicks or kitchen string. Brush the tenderloin with the remaining olive oil and season generously with salt and pepper on all sides. 
#7. Place the same skillet you used to cook the onion and apples on medium-high heat. #8. Add the pork tenderloin to the hot skillet and sear until golden on all sides, around 5-6 minutes. #9. Transfer the tenderloin to the preheated oven and roast until fully cooked through in the middle for 20-30 minutes. The internal temperature in the thickest part of the meat should read 155°F with an instant-read thermometer. #10. Remove the stuffed loin from the oven. As the pork rests for 15 minutes, cover it loosely with foil. Remove the toothpicks, slice, and serve with a few remaining walnuts on top and a fresh veggie of your choice. Enjoy!
