Line a baking sheet with parchment paper or Silpat. Combine all ingredients in a small bowl and mix well, making sure there are no lumps in the Parmigiano Reggiano.
Using a small spoon, scoop about ½ - 1 teaspoon of the parmesan mixture and place it in a small pile on the lined baking sheet. Use the back of the spoon to press into the parmesan to form a flat oval. Repeat with the rest of the parmesan.
Place in the oven for about 7-8 minutes, until the cheese is golden. Remove from the oven and allow to cool completely on the baking sheet. Store in an airtight container at room temperature for up to 5 days.
