This recipe uses mostaccioli, which is tube-shaped pasta that can be ridged or smooth and is usually about 2 inches long. Penne is another good alternative.
Cook pasta according to package directions, adding broccoli during the last 2 minutes of cooking time; drain. Rinse and cool. Toss with parsley.
Place half of pasta mixture in a 4-qt. glass bowl; top with half each of tomatoes, beef, and onions. Repeat layers once. Pour dressing evenly over salad. Cover and chill at least 2 hours or overnight. Top with cheese before serving.
For testing purposes only, we used Ken's Caesar Dressing.
