1 large pork tenderloin, I used one about 7-8 lbs, it was big! It should have a bone and a layer of fat on the bottom.
1 large yellow onion
1 can root beer
2 cups apple juice
Water
Garlic powder, Italian seasoning
Barbecue sauce
Buns or rolls
Spray the crock pot with a non-stick cooking spray. Slice the onions and layer them evenly in the bottom of the crock pot. Place the pork in the crock pot, fatty side up, pour in root beer, apple juice and water until the liquid is about 2/3 full. Sprinkle with seasonings. Let the meat sit in the pot, refrigerated, for a couple of hours then flip and sprinkle with seasonings. I put the pot on low at midnight so it was ready at 2:00 PM. When the meat reaches an internal temperature of 160 degrees, drain the meat, remove the bone and shred with 2 forks. Serve on rolls with BBQ sauce!
