Cook the rotini according to the package directions. Drain and rinse with cold water, then set aside.
In a large bowl, combine the mayonnaise, red wine vinegar, salt, red pepper flakes, oregano, Italian seasoning, garlic powder, and Korean seasoning. Stir until well combined.
Add the cooled pasta, Colby Jack cheese cubes, banana peppers, sliced cherry tomatoes, and chopped pepperoni to the bowl.
Top with Parmesan cheese and stir everything together until the pasta and ingredients are evenly coated in the creamy dressing.
Serve immediately or refrigerate for 1 hour before serving. Enjoy!
