Do you know these Japanese mizu nasu (water aubergines) ? The particularity is you can eat them raw.
Of course they can be cooked too, like here :
The wiki article in Japanese is very interesting. They explain that has been traditionally cultivated in Osaka for many years. I wonder if they are more common here than in the rest of Japan. In Summer, all local shops have them.
The simplest way : I slice them, salt, let a while and rinse. Then I use as a salad.
With sweet chili sauce.
