Prepare the ingredients:
1. Cut the chicken into 0.5-1 cm cubes.
2. Finely chop the onion into small cubes.

Place 1 tablespoon (10 g) of butter in a pan and heat over high heat.

When the butter melts, lower the heat and add the onion.
Sauté over low heat until the onion starts to turn translucent. (4-5 minutes)
***Be very careful not to burn the onion.***

Add the chicken and sauté over medium heat until the chicken is fully cooked. (2-3 minutes)

Add the rice and sauté over medium heat. (1-2 minutes)

Add 3 tablespoons of ketchup, the bouillon, salt, and black pepper to taste. Mix quickly. (30 seconds)

Serve it on a plate, shaping it into a dome using a cup.

In a bowl, mix the eggs, mayonnaise, and milk well.

Heat a pan over high heat.

Add the butter and spread it over the entire bottom of the pan.

Lower the heat to medium and add the egg mixture. Wait for 5 seconds without touching the egg.

Stir the egg for 10 seconds, as if making scrambled eggs.

Let the egg cook a little more.
***Ideally, leave the egg slightly undercooked for a soft texture, but it can be cooked fully or to taste.***

Using a spatula, carefully detach the egg from the pan.

Serve it over the rice by sliding it from the pan.

Decorate with ketchup and it's ready!
