Just cook the soba and top with the rest of the ingredients. To serve just add a drop of soy sauce.
To make the nori tagliolini ... well look here! For the onion weed... just forage it, wash and cut (you can eat the flowers, stems and bulbs... the lot!). I bought the salted sakura (cherry blossoms) here, I love them, a bit like salted capers really!
