Creating your Mardi Gras Pasta Salad is simple when you follow these steps:

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

2. Prepare the Vegetables: While the pasta is cooking, prepare your vegetables. Dice the bell peppers, halve the cherry tomatoes, shred the purple cabbage, and chop the red onion and parsley.

3. Combine Ingredients: In a large mixing bowl, combine the cooked pasta, diced bell peppers, cherry tomatoes, shredded cabbage, corn, red onion, and black olives.

4. Add Cheese: Gently fold in the mozzarella cheese, taking care not to break any of the cubes if using block cheese.

5. Dress the Salad: Pour the Italian dressing over the pasta salad. Toss everything together until the pasta and vegetables are evenly coated.

6. Season: Taste the salad and season with salt and pepper as needed. Adjust the dressing to your preference, adding more if desired.

7. Chill: Cover the bowl with plastic wrap or a lid. Refrigerate for at least 30 minutes to allow flavors to meld.

8. Serve: Give the salad a good stir before serving to redistribute the dressing and flavors.

Following these steps will yield a delightful and vibrant Mardi Gras Pasta Salad that is sure to impress!
