1. Cook the rice like a risotto: in a sauté pan, gradually add 2 glasses of water while stirring often. It should be slightly sticky.
2. Peel and cut the onion in half, then into 5mm wide pieces.
3. Cut the leek into 1cm wide pieces.
4. Pour 1/4 glass of water into a skillet with the broth, heat it up.
5. Add half of the onion and leek, and as soon as they soften a bit, add half of the chicken, 1 teaspoon of sugar, and 1 tablespoon of soy sauce.
6. Crack an egg into a small bowl and mix. When the meat changes color, pour the egg around the edge of the bowl and cover.
7. When the edges of the mixture are cooked, turn off the heat and let it sit covered for a few minutes.
8. Serve half of the rice in a large bowl, and slide the mixture on top; repeat the process for the second bowl.
