Then to the onions add water, soba noodle sauce or dashi powder, light soya sauce, mirin and sugar on medium heat. Stir continuously until sugar has dissolved. Cover with a lid and bring to a gentle boil.

When onions become translucent, beat the eggs. Then pour beaten eggs over the onions and add the spring onions. Lower the heat slightly and cover saucepan with lid again. Simmer for a few minutes and cook eggs to preference.

In the meantime while the eggs cook, place rice in a large deep bowl. Then place the onion and egg mixture over the steamed rice. Sprinkle a few slices of spring onions and sesame seeds (optional) over. Serve and eat immediately while hot.
