Cook the pasta according to instructions. After draining the pasta, add to a bowl and place in the freezer. Stir a few times to get the pasta to cool down. Remove from freezer when the pasta is cold.
Add the Italian dressing and gently toss. Start with 1/4 cup and add more to your desired amount of salad dressing to pasta ratio. Season with salt and pepper. Keep chilled in the fridge until ready to serve.
