As a meal supplement or for a meal on-the-go (easy to travel with), I am
hooked on Pure Protein nutrition bars from Worldwide Sport Nutrition. I have
no connection to them, just a big fan.  You can find them in
nutrition/GNC-type retailers, or call them at 1-800-854-5019.  I spoke with
a customer service manager on Tuesday who assured me that all flavors are GF
except for Blueberry Cheesecake (she has been asked for this information
many times, and was quite familiar with Celiac).  They are more filling than
a balance-type bar and don't have the fat/carbs you might get from other
food sources.  Just a suggestion...
