Jerry Sandusky -- Feasting on Wieners Behind Bars

It's Jerry Sandusky's lucky day -- because he just got transferred to a brand new jail ... and today's lunch is hot dogs ... and buns.

A rep for the State Corrections Department in PA tells TMZ, Sandusky was transferred to Camp Hill correctional facility in Lower Allen this morning from the Centre County Jail, where he had remained in custody since his trial.

According to the rep, today's lunch is hot dogs, sauerkraut, and of course ... baked beans.

Sandusky's expected to spend anywhere from 2-4 weeks at Camp Hill before he's transferred to his more permanent home ... state prison.

The convicted child rapist was also issued his jail "blues" today -- the jail outfit consisting of blue pants, a blue shirt, a white undershirt, socks, and tighty-whiteys. It's unclear if he's in the general population or if he's being kept in solitary for his own safety.

But he's not doing too bad -- we're told prisoners at Camp Hill stay in 8'x10' cells ... which is the same size as Conrad Murray's cell in L.A. County ... AFTER Murray got his upgrade.
