As of the new year, I will sometimes need to provide a cold vegetarian lunch for a group of kids.
It needs to be healthy vegetarian food. I can expect nut allergy issues (although I'm hoping to avoid all that), I'm hoping for no other allergy issues.
All I can think of is sandwiches, or vegetables and dips. Cold soup?
(Hopefully, after a few months, we'll move back to hot food.)
