Step 1: Cook the Pasta - Bring a large pot of salted water to a boil. Add the pasta and cook until al dente, about 8-10 minutes. Drain and rinse under cold water.

Step 2: Combine Fresh Ingredients - In a large mixing bowl, add the cooled pasta, halved cherry tomatoes, turkey pepperoni, diced red onion, chopped green bell pepper, mozzarella, Parmesan cheese, and sliced olives. Stir gently.

Step 3: Prepare the Vinaigrette - In a separate bowl, whisk together olive oil, apple cider vinegar, Italian seasoning, garlic powder, salt, pepper, and red pepper flakes until smooth.

Step 4: Dress the Salad - Pour the vinaigrette over the pasta mixture and toss gently until everything is coated.

Step 5: Chill and Serve - Cover with plastic wrap and refrigerate for at least one hour. Toss before serving for freshness.
