Food in costume?

I'm finishing up a velociraptor costume for a con in about 60 days...cutting it close but I'm really just hoping to finish in time!

First time posting here, but I plan to wear the suit for a pretty long time at the con. I don't really know exactly how long but it'll be quite a while. While the con has food, I can't eat any of it.

I'll be able to take the head off to get breaks and get water while wearing the head (although I'm not sure if I have to use the bathroom since the legs are what I don't want to take off). But what about food? To eat I have no problem with removing the head and hands, even unzipping the front down so I can get air while I eat. The costume has feathers though on the torso.

What should I think about taking to eat? The hotel is not connected to the center. So, no cooler. I have celiac so I can't take anything with grains or lecithins of any kind. I know this isn't a food community but I figured maybe someone here has some ideas for me. I don't want to take anything crummy or gooey either. I've got NO ideas. Everything I think of has to be refrigerated, that I can eat anyway. I can't eat any granola bars or Kind Bars or Lara Bars or anything like that. This just really sucks because there's just nothing good! :\

Thanks!
