Gather the ingredients.

Bring a large pot of lightly salted water to a rolling boil. Cook bow tie pasta at a boil until tender yet firm to the bite, about 12 minutes; drain. Quickly rinse the cooked pasta in cold water to stop it from continuing to cook; drain.

Mix cooled pasta, broccoli, tomatoes, sliced green onions, celery, red bell pepper, and green bell pepper in a large bowl.

Gently stir salad dressing and Parmesan cheese together in a bowl until evenly mixed; season to taste with sugar, basil, and salt.

Pour salad dressing mixture over pasta mixture; gently toss to coat evenly.

For best results, chill salad in refrigerator before serving to allow flavors to blend.
