Bring a large pot of salted water to a rolling boil. Cook the pasta according to package directions until al dente.

In a large mixing bowl, whisk together mayonnaise, sour cream, and pickle juice until smooth. Add garlic powder, black pepper, and fresh dill. Taste and adjust seasonings as needed.

Drain the cooked pasta thoroughly and rinse it under cold water to stop the cooking process.

Transfer the cooled pasta to the bowl with dressing. Add diced pickles, red onion, and cheese cubes. Fold everything together gently but thoroughly.

Cover and refrigerate for at least one hour before serving.
