Ellen, would it be ok to ask what the specific diet requires and what
options you may have? It's possible one of us can find a 'bread' that is ok
for it and a recipe to match since there might be an issue with the one
normally used.

Things in my mind are 100% whole wheat may work better and you could make it
at home then bring it with you. (If there is some sort of blessing over it
expected, perhaps the rabbi could do that on the side earlier?).

Your mental happiness at sabbath is as important as any other aspect of your
overall person heath. So, maybe if you can explain what it needs to be, one
of us can find out how to make it in a way that is acceptable for your
medical and overall person health needs?
