Making The Best Pasta Salad is simple if you follow these easy 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 cool.
2. Prepare the Vegetables: While the pasta is cooking, chop the cherry tomatoes, cucumber, bell pepper, and red onion. Slice the olives and mozzarella if necessary.
3. Make the Dressing: In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, Italian seasoning, salt, and pepper.
4. Combine Ingredients: In a large bowl, combine the cooled pasta, chopped vegetables, black olives, mozzarella, and parsley.
5. Add the Dressing: Pour the dressing over the pasta mixture. Toss everything together gently until well combined.
6. Taste and Adjust: Sample your pasta salad. Adjust the seasoning if needed by adding more salt, pepper, or dressing.
7. Chill (Optional): For best results, allow the pasta salad to chill in the refrigerator for at least 30 minutes before serving. This allows the flavors to meld beautifully.
8. Serve: Give it a final toss before serving to ensure all ingredients are well distributed.

By following these steps, you’ll create a vibrant and delicious pasta salad that will delight everyone at the table!
