First prepare the tofu:Remove both blocks of tofu from the container. Gently rinse and set each block on a plate or shallow dish. In a large pan on medium-high heat, add a little oil and the ground pork. Cook for a few minutes, using a spatula to help break the pork into small pieces.
Once the pork starts to brown, add the minced garlic and cook for another minute.
Add half the green onions and cook for another minute.
Then add the soy sauce, mirin, and sake (or chicken broth). Stir to mix.
Mix the cornstarch with ¼ cup water and pour into the pan.
Turn the heat down to medium. Add the miso paste and stir to mix and dissolve the miso.
Stir in the sesame oil. Then turn off the heat.
Pour the ground pork sauce over the tofu (divide the equally between the two blocks of tofu). Top with remaining green onions.
You can finish the dish with a sprinkle of roasted sesame seeds and chili oil if you’d like. Eat with rice and enjoy!
