Combine all ingredients (except cream cheese & garnish ingredients) in a 6 quart slow cooker. Cook on high for 3-5 hours or low for 5-7 hours - low temp works best.
When soup is done, remove the chicken, shred it, set it aside
Stir or whisk ROOM TEMPERATURE cream cheese into the pot until a smooth consistency is reached
Add chicken back in for another 10-15 minutes
Serve immediately with garnish ingredients and enjoy!
