This made the most amazing leftovers. I was so happy to have this sandwich again the next day for lunch!
Cut the pork tenderloins in half, season them on both sides with salt & pepper, then place the cut and seasoned tenderloins in your slow cooker.
Add the onion, garlic, and barbecue sauce to the slow cooker, and stir until everything is combined.
Set the slow cooker on high and cook the pork a minimum of 6 hours.
When the pork is tender, shred the pork by pulling the pieces apart with a fork, and stir the shredded pork into the accumulated juices in the slow cooker.
In the bottom of large bowl, whisk together the mayonnaise, sugar, vinegar, dry mustard, celery seed, salt & pepper.
Add the shredded cabbage, and toss everything to combine.
Pile 145g of pulled pork onto a sandwich thin.
Drizzle on extra barbecue sauce.
Top with 50g coleslaw.
Close up the sandwich, and enjoy!
