Tortelloni is a type of stuffed pasta common in northern Italy, with a shape similar to tortellini, but larger and with a cheese-based filling. It is traditionally stuffed with ricotta, Parmesan, leafy herbs or vegetables such as parsley or spinach, egg and nutmeg. Some variants replace the vegetables with other flavorful ingredients, such as porcini or walnuts. A common filling, especially in the provinces of Ferrara, Modena and Reggio Emilia, is a paste made mainly of pumpkin pulp and amaretti biscuits. When traditionally made with ricotta and herbs, after boiling it is often stir-fried with melted butter and sage leaves, and covered with grated Parmesan. As one of the few northern Italian pasta dishes with no meat content, it is a traditional dish for Christmas Eve.
