Omurice

1 cup cooked white rice
1/2 small onion, finely chopped
1/2 cup chicken breast or boiled ham, cut into small pieces
Butter
Ketchup in a squeeze bottle
2 large eggs
Salt and pepper

Fry the chopped onion until transparent in butter. Add the chicken or ham and cook until done. Add the rice and toss until heated through. Add about 2 tbsps. of ketchup and toss rapidly - you just want to color and flavor the rice, not make it soggy. Season with a little salt and pepper. Mound the rice on a plate in a sort of omelette shape. Start heating a knob of butter in the frying pan until the butter stops bubbling. In the meantime, crack the eggs into a bowl, add a little salt and pepper and whisk with a fork. Pour the egg mixture into the pan and make an omelette that is still slightly runny in the middle. As soon as it's done, carefully turn the omelette onto the mounded rice.
Squirt with a little ketchup on top. Serve immediately.
