Boil a large pot of water for the pasta. Add rigatoni and salt and cook to al dente or with a bite to it. Drain and reserve 2 ladles of pasta water.
While pasta cooks, heat extra-virgin olive oil in a large deep skillet over medium-high heat. Add sausage, brown and crumble it, then add garlic and onions and cook until tender 5 to 6 minutes. Add cranberry sauce and wine and stir to combine then reduce a minute. Add kale in bunches and stir to wilt down. Add the reserved pasta water. Season the dish with salt, pepper, and nutmeg to taste.
Add pasta to the pan with sausage and kale. Top pasta with cheese and toss with kale mixture to combine. Serve immediately with extra cheese for topping.
