Locatello Romano and Grana Padano Parmesan. Grana Padano is Parmigiano Reggiano that hasn't aged enough yet. Sort of like youngster parmesan. It has more moisture to it and for me, makes it taste better than it's older sibling.
I eat a substantial amount of cheese every week, it's a true weakness of mine. At work, I'll pop into a walk-in cooler and grab a handful of cubed Grana Padano every couple of hours.
