For the dough mix 125 g flour, baking powder, 1⁄2 TL salt, some pepper and 1 pinch of nutmeg in a mixing bowl. Puree 1 egg, 125 g cream cheese and oil with a hand mixer. Add to the flour mixture and knead to a smooth dough. Wrap in foil and chill for about 30 minutes.
In the meantime clean and wash the broccolini. Peel the shallots and cut them into thin slices. Heat 1 tablespoon butter in a pan. Sauté shallots and broccolini in it. Add about 5 tablespoons of water and cook for about 5 minutes until the liquid has evaporated.
Preheat oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer). Grease a rectangular tart mould (11 x 35 cm; alternatively round, 22 cm Ø) with lift-off base and dust with flour. Knead the dough briefly and roll out on a little flour, slightly larger than the tin. Place the dough in the mould, pressing the edges. Prick the base several times with a fork. Pre-bake in a hot oven for about 12 minutes.
For the icing grate the parmesan finely. Puree with 2 eggs and 125 g cream cheese. Season with salt and pepper. Spread the broccolini and shallots on the pre-baked tart base. Carefully pour the egg mixture over the tart. Sprinkle with pumpkin seeds. Bake at the same temperature for about 30 minutes. Let it cool down for a short time, remove carefully from the tin and cut into pieces.
