In a medium bowl toss together the shredded radicchio, sliced pepperoncini, and pine nuts. Add the red wine vinegar, olive oil and salt and pepper, to taste. Gently toss to combine.

Arrange the soppressata and provolone on a large, clean work surface and top with a thin slice of watermelon radish and a small spoonful of radicchio and pepperoncini mixture. If desired, top with a small teaspoon of Major Grey's Chutney.

Roll up each Soppressata to form cones and secure with a toothpick.
