They never did this for the Jewish kids, only for the Muslims. My kids would go with whatever I decide they will eat.
The minute I saw this list, I recognized the brands as being, at least most of them (I'd have to check the packages of the brands I don't use) kosher. That clued me in immediately to the fact that they were catering to MUSLIMS in their school. They would never bother to do so for just Jews.
