I may have said this before, but I am sure that there no-one in China over the age of eight who can't cook egg and tomato!
Some years back, I asked a group of 18 year old students to write me the instructions for any "Chinese" dish they could cook. 95% chose egg and tomato! I'd say for 96% of those, it was possibly the only thing they could cook.
It seldom appears on menus, but you can always get it. There isn't 1 in 1.4 billion people can't throw it together.
The downside is that for vegetarians. which I thank all the gods I'm not , it's the only dish they ever get!
Nothing wrong with it, though. And seldom served alone. The animals parts will be another dish.
