Combine the flour, dissolved yeast, sugar, olive oil and water and knead a soft dough. Smear it generously with more olive oil, cover with a towel and put it in a suitable container to rise until doubled in volume.
In the meantime, rub the chicken inside and out with salt and black pepper and put whole, unpeeled garlic cloves, rosemary bunches, salvia leaves and 1 bay leaf in its belly. You can put spices and garlic under its wings as well.
Roll out the dough onto a floured surface and put the chicken in its middle. Wrap it carefully, first on one side, then the other. Put it in an oven dish laid out with baking paper and bake in a preheated 320°F (160 °C) for 60-90 min. until ready.
The rule goes that every 2 lb (1 kg) of meat need 1 hour of baking. Serve with a garnish of your choice!
