Start by washing and drying the grapes (you can do this step the night before). Wash the grapes and then dry with a flour sack towel or paper towels.
Chop up the salted peanuts in a food processor or chop them with a knife - you want them finely chopped.
Melt the white chocolate morsels in the microwave at 50% power, microwave in 30 second intervals, stirring in between minutes, until melted.
Line baking sheets with wax paper.
To make the grape bites take one grape and dip it in the white chocolate half way, and then roll it in the crushed peanuts and set on the prepared baking sheets. Repeat until all the grapes are dipped - you might have to melt a little extra white chocolate and chop some more peanuts, I had to crush more peanuts to finish the bag of grapes (it all depends on how many grapes you have.)
