Tear off the leafy parts of the kale. Chop into small pieces. Boil a pot of water and cook kale for 2 to 3 minutes. Drain. Mix miso, olive oil and onion. Heat the miso mixture in a pan, use a spatula to break up the miso. Add kale, cook over medium heat, stirring, until sauce is mixed with kale, about 3 minutes. Add salt to taste if you wish.
