Take an average, every day pasta dinner to the next level with this sweet and creamy alfredo inspired sauce. Savory Philadelphia cream cheese, known for its rich smooth flavor, is combined with a bitter leek and tart apple fondue. Melted together in a saucepan, they form a thick, sticky penne sauce. It combines an Italian idea with French fondues and takes less than 15 minutes to prepare and serve. This dinner is bursting with warm, homey flavors.
