Slow Cooker Baked Beans

My boys love beans.  I am sure the song about tooting helps with this.  Boys will be boys.

3 cans (28 ounces each) vegetarian baked beans, drained

1 medium onion, chopped (1/2 cup)

2/3 cup barbecue sauce

1/2 cup packed brown sugar

2 tablespoons ground mustard 

 

Mix all ingredients in 3 1/2- to 6-quart slow cooker. 2 Cover and cook on low heat setting 4 to 5 hours (or high heat setting 2 hours to 2 hours 30 minutes) or until desired consistency.
