We really enjoyed Katzen's pasta salad this summer.

Ingredients:
1 (16 ounce) package uncooked rotini pasta (or penne, bowtie, or other chunky pasta)
1 (16 ounce) bottle Italian salad dressing
2 cucumbers, chopped
6 tomatoes, chopped (or one pint cherry tomatoes)
1 bunch green onion, chopped
4 ounces grated parmesan cheese
1 tablespoon italian seasoning

Bring a large pot of lightly salted water to a boil. Place pasta in the pot, cook for 8 to 12 minutes, until al dente, and drain.
In a large bowl, toss the cooked pasta with the Italian dressing, cucumbers, tomatoes, and green onions. In a small bowl, mix the Parmesan cheese and Italian seasoning, and mix into the salad. (You could use McCormick's Parmesan Herb Seasoning Blend instead - use the whole jar of 1.87 ounces.)
Cover, and refrigerate until serving.
