From The New Spanish Table. According to the author, though cannelloni may have their origins in Italy, they have become something of a Catalan national dish. Rather than ricotta fillings and tomato-based sauces, Catalon cannelloni dishes can be filled with fish, ground meat or spinach. No-boil lasagna noodles can be used in place of cannelloni squares. I love the raisins in this, but they're the only thing my son doesn't like about it, so go with your own best judgments about family preferences.
