Press the tofu for 15 minutes to remove excess moisture, then cut into 1-inch cubes.
In a small bowl, whisk together the white miso paste and coconut aminos with a splash of water until smooth.
Heat the toasted sesame oil in a large pot over medium heat and sear the tofu cubes until golden brown on all sides.
Remove the seared tofu from the pot and set aside on a plate.
In the same pot, add the minced garlic and grated ginger, sautéing for 1 minute until highly fragrant.
Pour in the vegetable broth and bring the liquid to a gentle simmer.
Add the shelled edamame and chopped baby bok choy to the pot, cooking for 3 to 4 minutes until the greens are tender.
Whisk the prepared miso mixture into the broth, ensuring it is fully incorporated without bringing it back to a hard boil.
Return the seared tofu to the pot and season the soup with sea salt and black pepper.
Garnish the soup with sliced green onions and serve immediately in deep bowls.
