Roughly chop swiss chard, seaweed, and mushrooms. Dice green onions and set 1/2 aside.
In a large pot on medium heat add 1 carton of vegetable broth, 4 cups water, green onions, seaweed, ginger and mushrooms. Cover and let cook.
After 5-7 minutes, taste and add salt and pepper (be sparing because miso will also add saltiness later on).
Add swiss chard and tofu cubes (see notes about adding crispy tofu!) and 1 cup more water and stir well. Cook on medium-high heat for 5-7 minutes.
Meanwhile, in a small bowl, heat up 2 cups of water in the microwave. Remove and add 4 tbsp of miso paste to the bowl and whisk well.
Turn the soup to simmer, add the whisked miso to the pot and stir well for 2 minutes.
Remove from heat, add to bowls and top with fresh green onions and seaweed gamasio seasoning. Enjoy!
Notes
*For crispy tofu, use a tofu press for at least 30 minutes to drain excess fluid; then cut block into cubes and place on parchment paper (with salt & pepper if desired) and spritz of avocado oil spray and bake at 375F for 15-20 minutes or until tofu cubes have a golden hue. You can then add the crunchy tofu to your soup!
