For some reason last night I turned to my roommate and said, "I have a craving for Burger King." After she made sure to check my pulse and ask me for my full name to make sure I wasn't hallucinating, she allowed me to get to my computer and scour a few fast food sites to see about the gluten free possibilities.
Now, I've never eaten at Taco Bell but many gluten eaters have told me that it is delicious, amazing, and awesome. It never really appealed to me -- I haven't eaten fast food in years (In-N-Out excluded, of course).
So when I began searching I decided to start with Taco Bell, and not Burger King, because I pass a Taco Bell every day to and from school. I did find an allergen list, here. Unfortunately, it looks like almost every single product save for perhaps five is listed as possibly causing sensitivity to Celiacs.
Basically: Celiacs, BEWARE! If you are brave enough to try, please let me know about your experience.
