BBQ Pork Sandwiches

I made these for dinner last night. Couldn't even taste the onions!!! Callie and Asher loved getting the rings of onions apart so even your kids could help make these. We froze a ton for someother day after lunch today. I got this from my slow cooker cookbook.

2 onions, sliced
4-5 pound pork roast
5-6 whole cloves
2 C water

Sauce:
1 large onion, chopped (I skipped this one, too many onions already)
16-oz bottle barbecue sauce

Put half of sliced onions in bottom of slow cooker. Add meat, cloves, and water. Cover with remaining sliced onions. Cover and cook on low for 8-12 hours (I cooked it on high for 5 hours instead). Remove bone from meat. Cut up meat. Drain liquid. Return meat to slow cooker. Add chopped onion (if using) and barbecue sauce. Cover. Cook on high for 1-3 hours, or low for 4-8 hours, stirring two or three times. Serve on buns.
