Serving Suggestion
Cook chicken mixture as directed; spoon into slow cooker set on LOW. Place buns in lined basket; surround with bowls filled with celery mixture and shredded cheese. Invite your guests to serve themselves so you can also enjoy the party!
Shortcut
An easy way to get the shredded cooked chicken is to use a rotisserie chicken purchased from your grocery store. Just shred it with 2 forks. You should easily be able to get 4 cups shredded meat from 1 rotisserie-cooked chicken.
Variation
Omit the blue cheese.
