Plus it's easy to cover more than one group with the same meal, that is, a vegan meal would be fine for a vegetarian inmate to eat. Kosher and Halal are theoretically very close, presumably some meat producers must comply with all the handling and prayers to certify as both, etc. Or, since it doesn't seem have been suggested previously, why not a Kosher, Halal vegan meal plan for all inmates? If it was nutritionally complete, it should be cheaper than even the presumably cheap meat-based diet most prisoners are currently fed...
