A reminder: Most mayonnaise has "modified corn startch" A.K.A. wheat. (gluten)
Careful!

Wouldn't it be nice if there were more gluten-free options out on the road?

Annnnnd, (I know this is a stretch but) for supported tours!

I've never come across a charity ride, event or the like, where there was a gluten-free meal alternative (rice pasta, plain tomatoe sauce anyone?) ...
