Mix all ingredients except milk and butter in a slow cooker.
Cover and cook on low 8-9 hours.
Stir in milk and butter. Increase heat to high. Cover and cook 10-15 minutes or until hot.
Notes
*I personally do not care for the pre-mixed frozen vegetables. Those carrots? Gross. My solution is to use an equal amount of vegetables that I do like (usually green beans, corn and peas).Adapted from Betty Crocker
