Trim the silver skin and excess fat from the pork tenderloin, use toothpicks to wrap in bacon. Hit it with pepper and grill indirect on medium heat. With all the bacon fat it flares up pretty easy so keep a close eye on it (which is pretty fun anyway because this is one of the best smelling recipes out there).
Also great to finish with your favorite barbecue sauce.
Remove the toothpicks and cut into 1-2" slices.
