Put flour, some salt, butter in pieces and 1 egg into a bowl and knead first with the dough hooks of the hand mixer, then with your hands to a smooth dough. Wrap the dough in foil and chill for about 30 minutes
Pour boiling water over peas in a bowl. Wash parsley, shake dry. Pluck the leaves from the stalks, except for a little to garnish, and cut them into thin strips
Cut the bacon into strips. Heat oil in a pan and fry the bacon strips for 1-2 minutes until crispy, remove. Whisk 3 eggs, cream and 3/4 of the parsley, season with salt, pepper and nutmeg. Roll out the dough round (approx. 30 cm Ø) on a floured work surface
Grease a tart mould (26 cm Ø) and lay it out, pressing down the edge. Cut off the protruding edge. Put peas and bacon, except for something to sprinkle, into the tin and pour egg cream over it. Halve the processed cheese corners horizontally and spread on the quiche. Bake the quiche in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for 30-35 minutes. Sprinkle with parsley and remaining bacon and garnish with parsley leaves
