This pasta dish is a good recipe to have on hand, cooking with ingredients you may already have in your pantry, refrigerator, and freezer. It is flexible in that you can use any small shaped pasta, such as the orecchiette or medium shell. And any greens in the refrigerator, spinach, swiss chard or even kale are all nice to use. If you are not a fan of sausage, you could use ground beef or ground chicken. In my house, I always have a large hunk of Parmesan cheese, but asiago or mozzarella would work too.
