Tender, fall-off-the-bone chicken! Skip the overnight refrigeration if you are in a hurry. For variety, eliminate the onion and substitute a quartered lemon or two, stuffed into the chicken cavity. Chef Shapeweaver had a good suggestion: Use Fajita Seasoning Mix #28011 as another variation. Thanks! The standard size slow cookers are a bit too small and a whole chicken won't fit. You'll need a 6-quart slow cooker for this recipe.
