Bring a large pot of lightly salted water to a boil. Add pasta and cook until tender, about 12 minutes. Drain.
Melt butter in a large frypan over medium heat. Add sliced kielbasa and fry until toasty at the edges. Drain excess grease and stir in the alfredo sauce. Stir in the pasta and season with salt and pepper. Serve with a sprinkling of Parmesan cheese.
