Begin by boiling a large pot of salted water over high heat. Once the water reaches a rolling boil, add the rotini pasta and cook according to package instructions, usually about 8-10 minutes or until al dente. Once cooked, drain the pasta in a colander and rinse it under cold water until cool. Set the pasta aside to fully drain and cool.

In a medium mixing bowl, add the softened cream cheese, mayonnaise, sour cream, pickle juice, milk, and salt. Using a hand mixer or whisk, blend these ingredients together until the mixture is smooth and creamy, about 2-3 minutes.

In a large mixing bowl, combine the cooled pasta, chopped Polish ham, diced dill pickles, and green onions. Gently fold in the creamy dressing, ensuring that all the ingredients are evenly coated.

Once everything is well combined, transfer the Ham Roll Up Pasta Salad to a serving bowl. If desired, sprinkle additional chopped green onions, fresh dill, and a light dusting of black pepper on top. Let the salad sit for about 10-15 minutes at room temperature before serving.
