Cut the egg tofu into small pieces and then coat with cornstarch. Since egg tofu is super fragile and jiggly, adding a bit of cornstarch can help prevent it from breaking apart.
Heat a pan and add some oil. Fry the tofu until slightly crispy and brown. Transfer out.
Add minced pork with some chopped ginger. Fry until the pork becomes completely golden brown, then add oyster sauce, light soy sauce, sugar, and salt. Combine well.
Place some mushrooms or any other vegetables you want in the serving pot, add half of the minced pork, then the pan-fried tofu, and finally the remaining minced pork.
Add 1/2 cup of water, cover, and simmer for 3 minutes. Sprinkle some chopped green onions before serving.
