Pizza Pasta Salad Recipe

Pizza Pasta Salad
16 oz. rotini pasta
1 cup pepperoni, diced (I used a 5 oz bag of the mini pepperonis to save time)
1 can olives, sliced
1 cup mozzarella, cut into small pieces (I usually use about 6 string cheeses-they work so great for this!)
1/4 cup Parmesan cheese
1 cup tomatoes, diced (I usually leave these out since my family is not a huge fan of tomatoes!)
1 bottle of Bernstein's Restaurant Recipe Italian dressing (I have tried several different kinds of Italian dressing and this one really is the best in this recipe-it makes it so yummy! It's not very expensive and I've been able to find it at most grocery stores.)

Thanks Butter with a side of Bread!!!
