Rub the salt, margarine and garlic into the chicken to season.
Heat up the oil in a casserole pot and add the onions, then the chicken until slightly brown on the outside (or juices sealed).
Add the mushroom bouquet garni, wine and stock.
Once boil, transfer to the oven at 180C, for 30 minutes to 1 hour, depending on how soft you want your meat to be.
Adjust seasoning when done.
