In a medium saucepan, heat the cream cheese, hot sauce and Ranch dressing over medium-low heat until melted and combined.
Sprinkle in the cheddar cheese a little at a time, and stir until it is melted and smooth.
Stir in the chicken.
To serve, spoon the hot melted cheese dip in to a bowl or a small warming crock and surround it with things for dipping- chips, celery and/or crackers.
Notes
OPTION: replace the Ranch dressing with blue cheese dressing and sprinkle blue cheese crumbles on top.
