Bring a large pot of salted water to a rolling boil. Add the tri-colored rotini pasta and cook according to package instructions, about 10-11 minutes, until al dente. Drain and rinse under cold water.

In a mixing bowl, combine the Italian dressing, lemon juice, Parmesan cheese, and parsley. Add garlic powder, onion powder, and season with salt and pepper. Whisk until well blended.

Add the cooled pasta to the dressing mixture and gently fold until the pasta is well-coated.

Transfer to a serving dish or keep in the mixing bowl. Chill in the refrigerator for about 2 hours before serving.
