Add everything except the cream cheese to the slow cooker.
Cook on Low until the chicken is tender and fully cooked.
Remove and shred the chicken.
Return it to the slow cooker.
Stir in cream cheese until melted and creamy.
Notes
Leave out the cream cheese for a lighter, dairy-free-style chili, or use your preferred dairy-free cream cheese alternative. Add jalapeños if your family likes extra heat.
