Buffalo Chicken Lettuce Wraps - Crockpot!

Why is it the minute I decide I want to eat better, I crave the worst possible things to eat.  I was craving Buffalo Wings.  I did some research and found this recipe online.  It is not my recipe, it is the brain child of Gina Homolka.  (A true food Goddess if there ever was one.)  I cannot believe How easy this recipe was, and satisfying too!  Two wraps with a 1/4 cup each of chicken is only 148 calories!  I found a low fat/low calorie Ranch dressing that was 30 calories a tablespoon.  I only used a teaspoon for each wrap.  I served this with my skinny baked french fries (one of my earliest postings) and I was very satisfied!  To make this you will need:
For the chicken:
2 boneless skinless chicken breast
1 celery stalk
1/2 onion, diced
1 clove garlic, peeled and smashed with you knife
16 oz fat free low sodium chicken broth
1/2 cup Frank's hot cayenne pepper sauce
For the wraps:
6 large Butter lettuce leaves
1 1/2 cups shredded carrots (buy the already shredded)
2 large celery stalks, cut into 2 inch matchsticks
Optional:  Low fat/Low Calorie Ranch dressing
1.)  In a crock pot, put chicken, onions, celery stalk, garlic and broth (make sure your chicken is covered in broth, if not add water).  Cover and cook on high 4 hours, or low for 8.
2.)  Remove the chicken from the crock pot.  Using two forks, shred the chicken.  Reserving on 1/2 cup of the broth, discard the rest.  Add the chicken back to the crock pot along with the reserved broth and the 1/2 cup of Frank's.  Continue to cook for another half hour.
3.)  Cut up the carrots and the celery.  Remove the stem from the butter lettuce and separate the leaves.  Using the lettuce as a wrap, add 1/4 cup of the chicken.   Top with some carrots and celery.  Top with Ranch dressing if using.  Roll it up and enjoy!
