Creating the Creamy Italian Pasta Salad is simple with these straightforward steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the rotini pasta and cook according to package instructions until al dente. Drain and rinse under cold water to stop the cooking process.

2. Prepare the Vegetables: While the pasta cools, chop the cherry tomatoes, cucumber, bell peppers, and red onion. Slice the black olives and cube the mozzarella cheese.

3. Combine Ingredients: In a large mixing bowl, combine the cooled pasta, halved cherry tomatoes, diced cucumber, chopped bell peppers, red onion, sliced olives, and mozzarella cheese.

4. Make the Dressing: In a small bowl, mix together the Italian salad dressing, mayonnaise, garlic powder, and Italian seasoning. Stir until well combined.

5. Mix It All Together: Pour the dressing over the pasta and vegetables. Gently toss everything together until all the ingredients are well coated.

6. Season to Taste: Add salt and pepper to taste, adjusting based on your preference.

7. Chill: Cover the salad with plastic wrap or a lid and refrigerate for at least 1 hour to let the flavors blend.

8. Serve and Garnish: When ready to serve, give the pasta salad a quick stir. Garnish with fresh basil if desired before serving.
