Bring a saucepan of water to the boil. Add the beans and the salt and cook for 3 minutes. Add the peas and cook for another minute.
Drain the vegetables, then rinse them under cold running water to stop the cooking process.
Squeeze the beans out of their pods and split them in half with your fingers.
In a large bowl, combine the radish, cucumber, beans, peas, ginger and sesame seeds. Season with the sea salt and sesame oil.
