Knead yeast and sugar with a spoon until the yeast is liquid. Knead the flour, 1 teaspoon salt, yeast and 300 ml lukewarm water with the dough hooks of the hand mixer to a smooth dough. Cover and leave to rise in a warm place for about 1 1/2 hours.
Onions peel and cut into short strips. Clean, wash and chop the peppers. Heat oil and fry onions for about 10 minutes while turning. After about 5 minutes add the paprika. Stir in olives.
For the cream, peel and finely dice the garlic. Wash the rosemary, shake dry, remove the needles from the twigs and chop finely, except for a little bit for sprinkling. Mix quark, crème fraîche, egg, garlic and rosemary.
Season with salt and pepper.
Quarter the dough, form quarters into balls, roll out oval (approx. 12 x 25 cm) and place on a baking tray lined with baking paper. Spread cream and onions on top. In a preheated oven (electric cooker: 250 °C/ convection oven: 225 °C/ gas: see
manufacturer) bake for about 15 minutes. Sprinkle with remaining rosemary.
