Dr. Conrad Murray's 1st Meal Behind Bars -- Super Cheeeeesy

He's barely been locked up a couple hours -- but TMZ has learned, Dr. Conrad Murray has already been offered a delicious sacked lunch behind bars ... including jailhouse-baked cookies.

Law enforcement sources tell TMZ, Murray's first meal contained a cheese sandwich, some fruit punch, a few carrot sticks, and some homemade Oreo-knockoff cookies ... baked in the jail's own bakery.

No word on whether Murray actually ate any of it, but we're guessing he didn't have much of an appetite.
