Slice each pear in half, removing the core and seeds, but leaving the skin on. Slice each half into 6 slices and toss with lemon juice. Set aside.
Beat the Gorgonzola and cream cheese until smooth. Season liberally with black pepper.
Cut the prosciutto slices into 3 pieces each, lengthwise.
Spread about 1 tablespoon of the cheese mixture on each of the pear slices, covering about ¾ of the pear slice. Wrap a piece of the prosciutto around the bottom half of each pear slice. Finish by pressing the pear slice into the chopped walnuts. The nuts will adhere to the cheese. (The finished pears may be refrigerated for up to an hour before discoloration appears.)
