Cook the Rotini: Start by boiling the rotini pasta as directed on the package. Drain and let it cool completely.

Prepare the Salad Base: In a large mixing bowl, combine the cubed cooked chicken, halved green and red grapes, and dried cranberries.

Mix the Dressing: In a small bowl, whisk together the ranch salad dressing and mayonnaise until smooth and well combined.

Combine the Ingredients: Add the cooled rotini pasta to the bowl with the chicken and fruit. Drizzle the dressing over the salad and mix well to ensure all ingredients are thoroughly coated.

Add the Cashews: Just before serving, gently fold in the salted cashews to retain their crunch. Enjoy right away, or refrigerate briefly to allow the flavors to blend beautifully.
