Cut the prepared mushrooms into medium-sized cubes and place them in a frying pan. Simmer over medium heat for 4 minutes. Add salt and spices.
Place the prepared rice in a frying pan and simmer along with vegetables and mushrooms for a minute. Add two cups of hot water, whole garlic cloves and cover with a lid. Simmer over low heat for 20 minutes until the rice is completely cooked.
