Preheat the oven to 450 degrees F. Line a baking sheet with foil and lightly coat with cooking spray.
Place the tomatoes in a single layer on the prepared baking sheet. Drizzle the tomatoes with the olive oil, and sprinkle them with garlic, oregano, salt and pepper.
Roast until the tomatoes are slightly shriveled and soft, 15 to 20 minutes. Roughly chop the tomatoes and set aside.
The Pasta:
While the tomatoes are roasting, cook the pasta according to package directions. Drain.
Heat a large skillet over medium-high heat and lightly coat with cooking spray. Cook the sausages until browned, 7 to 8 minutes.
Add the roasted tomatoes and cooked pasta to the sausage, along with the olive oil, salt, pepper, basil and parsley.
