Preheat the oven to 350 F. Spread the pepperoni on foil-lined baking sheet and bake in the preheated oven for 8 minutes. Remove from the oven and let cool.
Prepare the hot honey dressing. Add all dressing ingredients to a large jar with a lid. Shake well until combined (alternatively, you can also add ingredients to a bowl and whisk to combine).
In a large bowl, add the cooked pasta, pepperoni, cherry tomatoes, mozzarella, arugula, and basil.
Pour the dressing on top and toss to combine. Garnish with additional basil and serve.
