Clean and wash broccoli and cut into florets. Pre-cook in boiling salted water for about 5 minutes and drain. Peel onion. Heat the fat in a small pan and fry the onions briefly.
Let it cool down. Cut the ham into cubes. For the dough mix quark, 6 tablespoons of milk, oil and salt. Mix flour and baking powder, add and knead everything to a smooth dough. Grease a springform pan (26 cm Ø) and sprinkle the base with 2 tablespoons of breadcrumbs.
Roll out the dough to a circle (34-35 cm Ø) and line the mould with it. Prick the base of the dough several times with a fork and sprinkle with the remaining breadcrumbs. Put broccoli, ham and onions into the tin.
Mix eggs, remaining milk, cheese, salt, pepper and nutmeg. Pour into the mould and bake in the preheated oven (electric oven: 200°C/ gas: level 3) for approx. 11/4 hours. Cover if necessary in the last 15 minutes.
Let it rest in the mould for about 15 minutes before cutting. Results in about 12 pieces.
