To arrange salad add all ingredients to a large bowl and pour in half the dressing. Gently toss salad to combine. Pour remaining dressing and sprinkle with black pepper and fresh dill (optional). Gently stir to combine.
Cover salad and place in the fridge for at least an hour.
Notes
Add more ranch dressing if you like your pasta salad on the creamier side or if the pasta dries out slightly in the fridge.
