Heat a small pan over medium heat. Add your pine nuts to toast, stirring occasionally, until golden, 2-3 minutes. Set aside to cool.
For the vinaigrette, in a medium-sized mixing bowl, whisk together the minced shallot, Dijon, white balsamic vinegar, sherry vinegar, and garlic powder until combined. While whisking, slowly drizzle in the olive oil. Taste and season with Kosher salt and freshly ground black pepper, as needed. (TIP: I like my salad dressing to be very acidic. If it's too acidic for you, add in an extra tablespoon on olive oil.)
In a large bowl, combine the radicchio, arugula, Parmesan, olives, artichokes, salami, pine nuts, roasted peppers, and as much dressing as you’d like. Toss with Kosher salt and freshly ground black pepper to taste. Add more dressing, salt or pepper, if needed and serve.
