Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper.

Arrange the pretzels on the baking sheet. Add a slice of cheddar and a pepperoni to each pretzel. Transfer to the oven and bake for 10-15 minutes, until the cheese has melted and the pepperoni is just beginning to crisp. Remove and serve, top with asiago and parsley. The pretzels can be made 2 days in advance and served at room temperature or warmed up.
