The quality of prison religious meals

 When I was in federal, as well as state prisons, they would not accommodate me as a Zoroastrian.  I did notice something interesting with the accommodations made for kosher and halal meals.  They would serve one of four types of frozen meal from a brand called my own meals, which came with kosher and halal certification

 Notice how some of the meals include pinto beans and other types of beans, which are neither kosher or halal, including in the meals they served in prison.
​The fact is many inmates will claim to be jewish or muslim simply to make the prison system spend extra money on them.  Little is done about this, however some prison systems do a test of faith to make sure inmates are not lying about their religious background.
The bottom line is no matter your religious background you should know how to make due with whatever resources you have, including food.  If someone says they are jewish or muslim but do not know what is kosher or halal that is suspicious in itself, and they should not be accommodated, as it wastes resources on those who need the religious accommodations and makes things harder for them.
