Prepare the pizza dough according to our pizza dough recipe, or if using store-bought dough, let it sit at room temperature for 1 hour before stretching.

Preheat the oven to 500°F (or as high as your oven goes).

Dust a baking sheet with cornmeal. Place the pizza dough on the baking sheet and stretch it into a large circle or oval. Top with the mozzarella and sliced garlic.

Bake for 10 to 15 minutes, or until the cheese is melted and the crust is browned.

Meanwhile, make the red wine vinaigrette: In a lidded jar, place the olive oil, red wine vinegar, honey, mustard, garlic, oregano, salt, and several grinds of pepper. Cover and shake to combine.

In a large bowl, toss together the arugula, radicchio, and red onion. Drizzle with a little of the dressing and toss to coat, adding more dressing as desired. Sprinkle the salad over the pizza, then top with the pepperoncini, shaved Parmesan, and pinches of red pepper flakes.

Slice and serve.
