Boil the buckwheat noodles and rinse them in cold water.
Make the sauce by adding salt and pepper to soy milk.
Blanch the yubu (fried tofu pockets) in boiling water to remove excess oil.
Stuff the blanched yubu with the cooked buckwheat noodles and roll them up.
Pour the prepared soy milk sauce onto a plate and place the yubu rolls on top.
Garnish with vegetables or seaweed flakes as desired.
