Cook the pasta to al dente per the package instructions. Rinse and drain and transfer to a large bowl.
Add the pickle juice to the pasta and toss gently to coat. Let sit for 5 minutes then drain (but do not rinse!).
Add in the dressing and stir gently to coat.
Place in fridge for at least 1 hour before serving. I prefer to let the salad come to near room temperature before serving so that the dressing is not quite as thick.
