Cook pasta according to package instructions, reserving 1 cup of the starching cooking water.
While the pasta is cooking, head a deep skillet over medium-high heat and spray with cooking spray. Remove sausage from casings and add to the pan. Use a wooden spoon to break the sausage down into bite-sized pieces and cook until browned, about 8-10 minutes.
Add garlic to the sausage and heat for 30 seconds to release flavor. Stir in kale to the pot along with ½ cup of the starching cooking liquid reserved from the pasta. Cover pan with a lid to quickly wilt the kale.
Stir in the cooked pasta, white beans, olive oil and parmesan cheese. Check for seasoning and add salt and pepper to taste.
