Slice pork tenderloin into thin strips so they are approximately 1/4-inch thick, 4 inches long and 1.5 inches wide.
Add pork slices and BBQ sauce to a dish or sealable bag and allow to marinate in the refrigerator for at least 2 hours (longer if you have time).
Soak wooden skewers in water to keep them from burning on the grill.
Pre-heat grill or grill-pan to high.
Carefully slide each pork loin slice onto a skewer lengthwise so the meat stays flat and the skewer becomes the “rib.”
Place “ribs” on hot grill and pour any leftover BBQ sauce over the meat.
Cook 4-6 minutes on each side or until cooked to desired doneness.
