Follow directions on edamame package on how to cook them (I prefer boiling them a couple of minutes less than what the directions say, as it makes them less mushy). Drain them and let them dry for 2-3 minutes.
Break the nori and add it to a coffee/spice grinder along with the bonito flakes and the salt. Grind the mixture until it almost turns into a powder.
Put the edamame in a mixing bowl and sprinkle the powdered mixture over them. Toss a few times and serve.
