Pork and apple are a traditional combination, but there is no need to make applesauce when the apples are stuffed into the pork suck as in this Bacon Wrapped Tenderloin recipe.
Preheat a smoker to 225 degrees F (107 degrees C). Add the fruitwood chunks.
In a shallow skillet, cook the apples with the rosemary and a little bit of water over medium heat until just tender, 3 to 5 minutes. (Smoking the apples stuffed in the loin isn’t enough heat to cook them through.)
In a small bowl combine the BBQ sauce and apple juice to form a glaze. Set aside.
Layout the bacon slices side by side to create a large sheet.
Place the tenderloin on one edge of the bacon slices, perpendicular to the pork. Slice down the center of the tenderloin and fill with the prepared apples. Wrap the bacon up and over the pork and apples to completely cover.
Place the tenderloin seam side down in the smoker and cook until your preferred doneness, about 3 hours.
When the pork has almost finished cooking, brush evenly with the glaze. Cook for 10 minutes. Brush with glaze again and cook for an additional 10 minutes.
Remove the pork from the smoker and let rest 10 minutes before slicing.
