This recipe comes from the German translation of Time-Life's “Die Küche in Italien”, originally published in 1968. Apart from the horrible US cups and spoons measurements, it's pretty good. The main reason for this recipe is to get the measures straight and to adapt them to my personal tastes.

This recipe refers to others: fresh pasta, Béchamel sauce and salsa di pomodori.

300 ml	Salsa di pomodori	13
50 g	Parmesan cheese	13

Procedure

Start at least 90 minutes before serving.

1. Thaw the spinach if frozen. Obviously you can use fresh spinach too, but I don't know what quantity would be appropriate.
2. Finely chop the onion and start frying gently in the olive oil.
3. While the onion is frying, peel and crush the garlic and add to the pan shortly before the onion is dry. The mixture should not brown.
4. When the onions are done, add the spinach and continue frying until the moisture has evaporated. Reserve.
5. In the same frying pan, melt the butter and fry the meat until dry. Again, it shouldn't brown considerably.
6. When the meat is done, coarsely mince meat and onion and spinach mixture to get a uniform mixture.
7. There should be enough butter and fat left from the meat to fry the chicken liver. Fry until barely firm; the livers will cook further in the oven. Chop coarsely and add to the filling.
8. Whisk the eggs and add to the filling.
9. Add cheese, cream, oregano, salt and pepper to taste. Mix thoroughly.
10. Cook pasta and chop into sheets about 15 cm square.
11. Coat the bottom of an oven dish with sauce béchamel and place the cannelloni in them:

    

12. When finished, cover with the remaining béchamel and leave to cool. The sauce will form a tough skin which makes the next step easier.
13. Cover the surface with salsa di pomodori. Sprinkle with parmesan cheese and bake for 30 minutes.
