To a skillet set over medium heat, add the sausage. Cook until browned, approx. 10 minutes, breaking it into pieces as it cooks. Drain on a paper towel-lined plate. Set aside.
Meanwhile, cook the tortellini according to package directions. Drain, rinse, and set aside.
In a small skillet over low heat, toast the pine nuts until lightly golden brown. Transfer to a small bowl and set aside.
In a large mixing bowl, combine the pasta, sausage, pine nuts, sun-dried tomatoes, scallions, and parmesan cheese. Toss to combine. Add the salad dressing and toss to coat.
Serve warm, at room temperature, or chill and serve. Salad will keep in the refrigerator for 3-4 days.
