Preheat oven to 400 degrees. Place squash on a large baking sheet and drizzle with 1 T. of olive oil. Season with salt and pepper to taste. Roast for about 25 minutes, until tender.
Meanwhile, boil pasta according to package directions.
Heat 1 T. of olive oil in a large, deep skillet over medium high heat. Add onion and cook until softened. Add sausage and cook, crumbling to keep the pieces small, until cooked through.
Stir in kale, garlic and rosemary. Cook until kale is wilted. Add squash and drained pasta and mix again until all ingredients are evenly distributed.
Add grated parmesan and stir one more time until the cheese is incorporated.
