First crumble the yeast and add to the mixing bowl with the sugar and water. Heat 2 min. / 37° /level 2.
Add the oil, salt, and flour and knead 4 min. into a dough. (Don't be surprised, the dough is very crumbly).
Knead the yeast dough into a ball on the work surface, place in a lightly floured bowl, cover and leave in a warm place for approx. 45 mins. Please note: Yeast dough does not tolerate draughts.
In the meantime, prepare the filling:
To do this, cut the chicken inner fillet into cubes and fry in a pan with a little salt and pepper. Set aside.
Then clean the mushrooms with a soft brush, remove the stem ends and cut into slices.
Next, peel and quarter the onion and peel and halve the garlic clove.
Rinse the mixing bowl.
Then add the onion and garlic to the mixing bowl first and chop 5 sec. / level 5. Use the spatula to push everything down from the edge of the mixing bowl and repeat the process.
Add the butter and steam 3 min. / 120° / level 1.
In the next step, add the tomato purée and mushrooms to the mixing bowl, remove the measuring cup and steam 4 min. 30 sec. / 100° / anticlockwise rotation / level 1.
Finally, mix the sour cream with the cream and eggs in a bowl using a whisk. Then season with salt and pepper.
Completion:
At the end of the cooking time, preheat the oven to 200° C top/bottom heat.
Place the yeast dough in the quiche tin and roll out, pulling up the edges.
Then fill with the chicken and mushrooms and pour over the sour cream and egg mixture.
Sprinkle with cheese and bake in the lower third of the oven for 35 minutes.
Garnish the quiche with fresh parsley and serve.
