Wash the bean sprouts thoroughly and drain the water.

Cut the tofu into slices of appropriate thickness.

Pat the tofu dry with kitchen towels.

Sprinkle a bit of salt on both sides of the tofu.

Slice the onion, green onion, and green chili into appropriate sizes.

Mix the seasoning ingredients in a bowl to create the sauce.

Layer the bean sprouts at the bottom of a shallow pot, followed by onion slices.

Place the tofu slices on top and pour the prepared sauce over them. Add 1 paper cup of water around the edges.

Bring the pot to a boil and stir the sauce occasionally, spooning it over the tofu.

Add green onion and green chili, then reduce the heat to medium-low and simmer.

Crack an egg into the pot, cover with a lid, and cook for about 3 minutes.
