Cook in your crock pot for 7-8 hrs on low setting. After 7-8 hrs DRAIN ALL BUT 1 CUP liquid from crock pot. I put a large bowl under a colander to save the onions. Then reserved a cup of liquid and put the onions in colander back in crock pot.Shred pork with two forks. Pour reserved liquid,onions and remaining bbq sauce in. Cook on high for 30 minutes. Your done!
