Prep time: Less than 5 minutes + 10 minutes later
Cook time: 8 - 10 hours + 1 hour later
1 large onion, sliced
3 lb Boneless Pork Shoulder Roast
2 C (16 oz) ginger ale
16 oz BBQ sauce
1 package sandwich buns (8 count)
Place half of the onion in the crock pot. Put the meat on top of the onion layer. Layer the other half of onion on top of the meat. Pour ginger ale on top.
Cook 8-10 hours on low.
Remove meat from pot. Discard liquid and onions. On a plate, pull the pork for the sandwiches. Place the pork back into the pot and cover it with the BBQ sauce.
Let it cook on low for another 30 minutes to 1 hour to let the BBQ sauce heat.
Serve on buns.

My Notes:
This was great - officially part of our regular rotation.
