Penne with Spicy Sausage and Greens

Preheat the oven to 350 degrees. Spray a 2 ½-quart baking dish with nonstick spray.

Bring a pot of salted water to a boil. Add the pasta, and cook for 8 minutes. Drain.

While the pasta is cooking, heat a large skillet over medium and spray with nonstick spray. Add the sausage, and break it into small pieces with a wooden spoon. Let it cook, undisturbed, for about 4 minutes. Stir, and cook for another 4 minutes or so, or until the sausage is cooked through. Add the garlic and stir, and cook another 1 minute. 

In a small bowl, stir together the cream, crushed tomatoes, dry mustard, salt, and pepper. Stir in the cheddar cheese and ½ cup of the parmesan cheese. Add the mixture to the skillet with the sausage, and stir to combine. Stir in the greens, and then the cooked pasta. 

Transfer to the baking dish, and top with the remaining ½ cup parmesan. Bake for 25 minutes, until the cheese is bubbly. Let stand 5 minutes before serving.
