Mix yeast with sugar and some lukewarm water. Put flour and salt in a bowl. Press a depression in the middle and add the yeast. Dust with some flour and let it rise for 15 minutes. Add olive oil, white wine and 1/4 litre lukewarm water.
Knead everything into a smooth dough. Leave the dough to rise in a warm place until the dough has doubled. Cut the sausage into thick slices. Knead the dough again, roll out to a rectangle (38 x 42 cm) on a floured work surface and place on a greased baking tray. Prick several times with a fork. Leave to rise for another ten minutes. Cover the dough with the sausage slices. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 25 to 30 minutes. Cut Coca-Sabrasada into pieces. Arrange on a plate.
