She's about as Jewish as she is Russian.
24,000 incarcerated people in the U.S. eat kosher meals. Even some neonazis. Why?

But why would incarcerated people who aren’t Jewish want kosher meals to begin with? Siporin writes that one reason is that they often come prepackaged, which can make them a valuable commodity in the prison economy. Some incarcerated people also believe that kosher diets are healthier or better tasting than the regular prison fare. And some say they contain more calories, something very desirable for those who want to build muscle. Siporin’s research suggests that this may sometimes be true, but probably isn’t usually the case.
Another reason for eating kosher may be that the power to successfully demand a particular diet may give inmates some sense of control in a situation where they have very little of it.
“Paradoxically,” Siporin writes,
“by submitting themselves to an external discipline (kashrut), they gain some leverage over the prison administration, the powerful entity that controls their daily lives.”
