Easy Barbecue Ribs

3-4 lb. baby back spareribs (These work better with the bones vs country-style)

2 onions sliced
16-24 oz. bottle barbecue sauce (I love the Tony Roma's Brand Carolina Honey's.  You can find it at any grocery store)

Place the ribs in your crock-pot.  Put onions around the ribs and cover with the barbecue sauce.  Season with Salt and pepper.  Cook on high for 1 hour, then turn to low and cook for 8 more hours.  

These are so good, easy and very tender!
