Prepare grill by adding three pounds of applewood charcoal on the bottom and to one side of your grill.
Light the grill and allow the charcoal to become glowing orange.
When the grill is hot, between 475 and 500 degrees brush the rack with vegetable or canola oil.
Place the pork about five (5) inches away from the coals; cook the pork using indirect heat.
Close the lid and cook for fifteen up to twenty minutes.
Open the lid and turn the pork 180 degrees with the side that was facing the coals now turned away.
Close the lid and allow the pork to cook for an additional fifteen or twenty minutes.
Using an instant-read thermometer check the temperature of the pork; it should read between 140 and 145 degrees.
Remove the pork from the grill and onto a cooking sheet.
In the kitchen allow the pork to rest for fifteen minutes.
Slice and chop the pork into small bite-size pieces.
Serve.
Reserve leftover pork for next day lunch or dinner.
