Hi Anne,
You probably couldn't find it because they're all listed as parmesan peppercorn (not peppercorn parmesan). Here's one for you:
George's Wilson House Parmesan Peppercorn Dressing
1 package Kraft or Hidden Valley ranch dressing mix, prepared according to package directions
1 tablespoon freshly cracked black pepper
3 tablespoons freshly grated Parmesan cheese
Combine ingredients and mix well. Keep refrigerated. Makes about 21/4 cups.
