This makes so much.  So that is why I suggest only using two large chicken breasts.  By the time you add the cheese and cream cheese into the meat it makes plenty for 4 larger hoagie size sandwiches.  One important tip with this is do not add any additional liquid to the crockpot.  It turns out juicy and yummy.  Even my picky daughter gets excited for this meal.  I don't love the name, but just be warned it is addicting!
