1Shred the yeast and put in a bowl with water.
2In a bowl, mix the flour with the salt and oil. Add the yeast and water mixture and knead for about ten minutes until getting a smooth and elastic dough. Make a ball and put it in the bowl to rise, covering it with a cotton cloth for at least an hour or until it doubles its size.
3Meanwhile, prepare the filling. Dice the onion and fry it with a little oil. Add the thoroughly cleaned mushrooms and saute. Once off the heat, add the crumbled spicy sausage.
4Put the dough on the slightly floured work surface and cut into 8 servings (more or less depending on the size of the rolls you wish to make). One by one, roll them into balls.
5Flatten slightly and add filling to each of them. Close the parcels, giving them the desired shape (rounded or elongated). Put them on the baking tray, leaving space between them, as they will grow. Cover and let them rise for another hour. Meanwhile, pre-heat the oven to 200 degrees Celsius. Before placing them in the oven sprinkle with a little flour.
6Bake for about 30-35 minutes, depending on their size. Remove them and let them cool on a rack.
