Cut the ham into small cubes. Peel onions and garlic. Finely dice onions, press garlic through a garlic press. Heat 20 g fat. Fry half of the onions and garlic in it. Add spinach and bring to the boil over medium heat. Cover and continue to cook over medium heat for 2-3 minutes, stirring occasionally. When the spinach is defrosted, add the ham and continue cooking for 6-8 minutes until there is no more liquid in the spinach. Stir in the ricotta, season with salt, pepper and nutmeg and leave to cool (at least 1 hour)
Heat the oil in a pot, fry the remaining onions and garlic in it. Add broth, strained tomatoes, tomato paste and oregano and bring to the boil. Simmer open over medium heat for about 5 minutes, stirring occasionally. Season tomato sauce with salt and pepper
Coarsely chop the onion rolls in the universal chopper and mix with the cheese. Grease a large, tall casserole dish. Put the cooled spinach ricotta filling in 2 portions in a large piping bag without spout. Fill the cannelloni with it and place in the casserole dish. Heat the tomato sauce again, pour over the cannelloni and sprinkle with the breadcrumb and cheese mixture. Spread 20 g fat in flakes on top. Bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 30-35 minutes until crispy
Waiting time approx. 50 minutes
