Penne With Black Kale, Sausage, and Roasted Peppers

Bring a large pot of salted water to a boil. Meanwhile, heat olive oil in a large, deep skillet over medium heat; add sausage. Cook until browned and halfway cooked through, about 7 minutes. At this point, add pasta to boiling water, stir a few times, and cook according to package directions. Add kale to sausage; cover skillet and cook 2 minutes, tossing once or twice, or until kale is wilted. Stir in peppers and garlic; cook 7 minutes longer, or until sausage is cooked. Drain pasta, reserving 1/2 cup of the cooking water. Return pasta to pot; add sausage mixture and reserved cooking water, and toss. Divide among 6 plates and sprinkle each with Parmesan cheese. Serve immediately.
