Add the finely chopped peppers and the onions, lightly braised in advance. Optionally, you can fry the onions and mushrooms together. Season with all purpose spices, salt, black pepper and a little savory.
Top up with a little water in the tray and put the dish to bake in an oven heated to 356°F (180 °C). Finally, sprinkle the juicy chicken with mushrooms, cheese and potatoes with a little grated cheese and parsley.
