Add all of the dressing ingredients to a bowl and whisk until combined and emulsified. Set aside.
Place a skillet on the stove over medium heat and spray with a little oil. Add the pepperoni slices and cook until crispy on both sides (approximately 3-5 minutes). Remove from the heat and set aside.
To assemble, add all of the salad ingredients to a bowl. Pour the dressing over the salad and toss to combine. Serve right away...with pizza on the side.

Notes
I got my vegan pepperoni at Trader Joe's. It isn't necessary to cook the pepperoni, but I think it tastes better when it is crispy.
I used Follow Your Heart vegan parmesan.
This is best served right away since the greens will continue to wilt as it sits.
The radicchio adds a slight bitterness to the salad, which is why the dressing is so tangy.
