DiGiorno makes a decent frozen pie, so I thought, how bad could this stuff be? I don't even like a pre-shredded cheese, but the next nearest grocery is 15 miles away. I should have waited. This grated stuff sat on top of my pizza for nearly 20 minutes and still came out hard, unmelted, and not all that flavorful. Save your money and buy a block of decent parm, because this stuff might as well be made out of plastic.
