Eggs and Tomato dish from North China

When I lived in a northern Chinese province I ate this dish a lot, it was one of the Chinese dishes that us Westerns seemed to like.

About 3- 6 tomatos, or a can of them
2-4 eggs
salt
4 table spoons of oil
1/2 tsp shredded chives/spring onions etc
1/2 tsp fresh shredded ginger
1 1/2 tsp sugar

1. Cook tomatos and take off the skins (or open the can)
2. Beat eggs with salt
3. Heat 2 table spoons of oil in fry pan until surface ripples. Pour in eggs and stir as they cook. Take the egg out. Put the rest of the oil in and heat it up. Add chives and ginger, stir fry for few seconds. Next add tomato, salt, sugar. Stir fry for half a min then put the eggs in too. Stir and it's just about ready to eat.
