Elevate your pork tenderloin by stuffing it with a delicious bacon and spinach filling. Use the food processor to blend together cooked bacon, spinach, cream cheese, and seasonings until smooth. Cut a slit along the length of the pork tenderloin and stuff with the bacon and spinach mixture. Secure with kitchen twine and air fry until the pork is cooked and the filling is heated through. Slice and serve with your favorite sides.
