Wrap the tofu with a kitchen towel to remove excess moisture.
Mix soymilk and Greek yogurt together in a bowl.
Mash the tofu finely, then add to the soymilk and Greek yogurt and mix well.
Season the tofu mixture with salt and pepper.
Blanch the yubu (fried tofu skin) briefly in boiling water to remove excess oil.
Stuff the tofu-soymilk-Greek mixture into the yubu pockets.
Place on a plate and top with desired toppings (e.g., seaweed flakes, chopped vegetables, etc.).
