Here is another recipe for baked beans in the crock pot. I copied this from a 2005 newsletter, but no longer have the name of the person who submitted it. I have left out the soy sauce on some occasions, if I did not have any on hand.

Baked Beans with Pineapple for Crockpot

In a skillet, brown beef; drain. Transfer to a 4 to 5-quart slow cooker. Add remaining ingredients and mix well. Cover and cook on low for 4-8 hours or until bubbly.(Really only needs to be heated up.) Serve in bowls. 6 servings
