Cook the rice according to package directions and let it cool.

Heat the oil in a heavy saucepan over high heat.

Brown the cubed lean pork quickly in the hot oil.

Add chopped onions, crushed garlic, salt, pepper, sambal, powdered ginger, and optional Indonesian spices (laos, ketoembar, or trassi) to the pan.

Sauté the mixture for 5 minutes until the onions are softened and fragrant.

Add leeks cut into rings and sauté for another 2 minutes.

Add the cooled rice to the pan and cook for a few minutes over high heat, stirring constantly to combine.

Incorporate baby shrimp, ketchup or soy sauce, and finely chopped celery tops.

Heat the mixture through until the shrimp is cooked and everything is well combined.

Serve hot, garnished with sliced tomatoes and gherkins, and optionally topped with a fried egg.
