Cook the rice in salted water as usual. Clean the chicken livers and cut into bite-sized pieces. Peel and finely chop the onion. Clean the mushrooms and chop if necessary.
Heat some oil in a coated pan. Sauté the onion in it until transparent. Add the mushrooms and fry until all the liquid has evaporated. Turn back the heat.
Add the poultry liver and braise for 10 minutes with the lid closed. Stir from time to time.
Pour on the cream. Season to taste with salt, pepper and the instant broth. Serve with the rice.
