Recipe: In a large heavy skillet, heat the butter and olive oil and saute the garlic, onion, artichoke, prosciutto, and sun-dried tomato for 3-4 minutes. Deglaze with the white wine and cook for 2-3 minutes more, until the wine evaporates. Add the cooking cream and reduce the cream sauce to about two-thirds. Season to taste and add the spinach one minute before the penne. In the meantime, boil the penne according to the package instructions and toss it with the Florentine sauce. Add some grated Grana di Padano cheese to the sauce, if desired. This recipe is for 4 portions of Penne Florentine.
