Preparation

For Salsa De Pomodori: Heat oil in a large pot. Add onion and cook 7-8 minutes or until soft. All all remaining ingredients for sauce. Cover and cook over low heat for 40 minutes. Press through a sieve. Set aside.
For filling: Heat oil in large frying pan. Add onion and garlic, cook until soft. Stir in spinach. Cook 3-4 minutes or until all moisture is boiled away and mixture begins to stick. Move mixture to a large bowl. Melt 1 T butter and cook livers 3-4 minutes until firm and lightly browned, but pink inside. Chop coarsly and add to spinach mixture (note as I said, I always leave this step out). Melt remaining butter and brown beef. Add to spinach mixture. Add cheese, cream, eggs and oregano to mixture. Mix and season to taste.
For Besciamella: Melt butter in large saucepan over high heat. Reduct heat to medium and add flour. Stir constantly to form a roux. Stir for 1 minute. Pour in milk and cream stirring constantly. Return to high heat and cook, stirring constantly. When sauce boils, reduce heat and cook 2-3 minutes, until sauce is thick. Season to taste.
To assemble: Place one cup of Salsa Di Pomodori in bottom of a sprayed 9x13 baking dish. Stuff each shell with 2-4 tablespoons of filling. Place in pan. Cover with remaining Salsa De Pomodori. Pour evenly Besciamella over the red sauce. Bake at covered with foil in a 350 oven for 45 minutes or until bubbly.
