i use parchment paper on paper plates. they must get tremendously hot because they melt into styrofoam plates, and i read in someone's recipe that she cracked the glass plate in her microwave nuking the cheese on the glass. i cut cheddar into squares about 1 inchx1inch and 1/4inch thick and nuke on high for about 1 minute in my smallish microwave. sometimes they peel off the paper and sometimes they stick. doing grated cheese on the stove top in a frying pan is just as tricky, IMHO, cuz you have to watch them and then flip them to get them nice and crisp.
