Preparation Cook penne in boiling salted water in a 5- to 6-quart heavy pot until al dente or according to package directions, then drain in a colander. Combine butter, oil, and pine nuts in cleaned and dried pot and cook over moderately high heat, stirring, until nuts are pale golden, about 3 minutes. Add garlic and cook, stirring, until garlic is golden, about 1 minute. Stir in greens and cook, stirring, until they wilt, about 3 minutes. Add penne, salt, and pepper and toss to coat. Stir in cheese and serve immediately with additional cheese on the side. Cooks' note:To reduce the start-to-finish time, cook the nuts, garlic, and greens in a separate pot while you boil the pasta.
