Cut the tofu and eggs into appropriate sizes.
Boil the eggs until they are soft-boiled, then peel them.
Blanch the tofu in boiling water, then remove excess moisture.
Mix soy sauce, vinegar, sugar, water, garlic, and spicy green chili peppers to make the pickling sauce.
Place the tofu and eggs in an airtight container and pour the pickling sauce over them.
Let it marinate in the refrigerator for at least 6 hours.
