It's not too fatty in general. It has about 75 calories per roll (not counting the oil spray) but don't forget to add calories for your blue cheese dressing if you use it as dip. If I made 12, it would be difficult to limit myself to only 1 or 2.
I make a very similar wrap that uses much more broccoli slaw, spinach, sometimes tomatoes, and a high fiber wrap. It's more filling because it's larger, but it's super satisfying for the buffalo flavor. Also, the buffalo chicken dip from skinnytaste is really good with celery.
