I would suggest a trip to the REI website to look at REI's freeze dried food. Left hand column has a filter for vegetarian, vegan, gluten free... Once you have a good feel for that food realm, buy some and see if it would work over weeks. I have some, but I’m not a vegetarian and I don’t have Celiac Disease, so I go with chicken, beef and wheat, along with the Pad Thai, rice and granola.
