Chop the onions, mushrooms and livers finely. Heat a little oil and braise the onions. Add the rice and stir. Once the rice changes its color a little, add the mushrooms and livers.
Stir and let them braise. Season with salt and the spices. Pour in the warm water and leave on the heat until the water boils off. The rice should be almost ready by now. Clean and salt the chicken inside and out.
Carefully lift the skin on the back and legs of the chicken with your fingers. Stuff the chicken's belly with the mixture, as well as the space between the skin and meat. Put the chicken in an oven bag and cut off the 2 ends of the bag.
Tie them off and bake in a preheated 392°F (200 °C) oven for about 2 hours. Grease will drip from the chicken into the oven dish. If you'd like to use it, you can add potatoes and carrots around the oven bag 30 min. before taking the chicken out of the oven.
