Clean and wash the carrots and peppers. Cut carrots into thin slices, peppers into thin strips. Mix quark, 2 eggs, oil and salt until smooth. Mix flour and baking powder and pour it over the quark and work it into a smooth dough with the dough hooks of the hand mixer.
Roll out on a floured work surface to a circle (26 cm Ø) and place in a greased pie mould (24 cm Ø). Prick the pastry base several times with a fork. Layer the vegetables in the mould.
Mix cream, remaining egg and egg yolk and season with salt, pepper, paprika and nutmeg. Pour over the vegetables and spread some chervil leaves on top. Bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for about 40 minutes.
