Glampingbaba's Easy Pulled Pork

Wow was this easy, fast and delicious on fresh baked bread with butter.  Threw this in a crockpot at noon and it was ready when I came home for supper.  Wish I had made coleslaw.

11/2 kg. pork shoulder blade roast
1 onion
1 botttle Kraft Chicken n' Rib Barbecue sauce.

Slice onion and put in bottom of crockpot, set roast on top, 1 bottle barbecue sauce mixed with 1 cup water poured over roast. cover and set on High for 5 hours.  No fuss....my kinda cookin'.
