"Court keeps alive inmate's quest for pork feast."

Headline at the National Law Journal makes the "quest" sound more absurd than it is. The prisoner, Derek Kramer, is an Odinist and he's suing in pursuit of his rights under the Free Exercise Clause and the Religious Land Use and Institutionalized Persons Act.

From the 7th Circuit court's opinion (PDF):

Odinism is a polytheistic religion, which was practiced for millennia in northern Europe before the rise of Christianity and has been revived in recent decades. The practice of Odinism includes group worship ceremonies. Pork is a sacred food to Odinists....

Specifically, Kramer asked for a feast on December 21st for the “High Feast of Yule” and “further requested that HAM/PORK be included in with the FEAST MEAL.”...

Kramer had a larger problem with the group worship at the Green Bay Correctional Institution: The Department of Corrections lumps the "Pagan" religions together for group worship purposes, and he objected to a specifically Wiccan ritual at the service. The demand for an annual pork feast was part of a larger effort to separate the Odinists from the Wiccans.

Kramer's loss on everything but the pork feast (which he hasn't yet won) is based on procedural matters that are probably only interesting to lawyers — unless you know how to be interested in the way procedure can operate to undermine rights.
