Preheat the oven to 250ºF.
In a large mixing bowl, add the Rice Chex, Corn Chex, pretzels, and peanuts.
In a medium size bowl, combine the melted butter, olive oil, hot honey, pepperoncini brine, garlic powder, onion powder, dried oregano, smoked paprika, and finely grated parmesan. Add to the dry ingredients and toss to coat.
Prepare a baking sheet with cooking spray. Spread the mixture out into an even layer on the baking sheet.
Bake for 60 minutes, tossing every 15 minutes. Let cool on the baking sheet, then transfer to a serving bowl. Add the parmesan crisps and toss. Serve and enjoy!
