prison "nutraloaf": i wonder if this is vegetarian

several blogs have been posting about this stuff: "nutraloaf".   Apparently, it's so uniform and flavorless that prisons use it to punish some inmates. 
I highly doubt it's vegetarian, considering how cheap meat can be. 
Can vegetarians get special consideration under "religion" if they go to prison? I believe Muslims can get meals made without pork.  I guess if i can't do the time i shouldn't do the crime.

please post info on nutraloaf, if you have any, in the comments.
