Combine everything listed above and place in a crockpot that has been sprayed with cooking spray. Cook on low for 4 hours. It will not matter if it cooks longer. If you double the recipe, you will need a larger crockpot, and it will need to cook longer.
Depending on the size of your crockpot, this recipe may make too much for one crockpot. Any additional dressing or all of it can be baked in the oven on 350 degrees for about one hour.
