Cook the ramen noodles as directed on the package. Divide between two bowls.
In a small bowl, combine tahini, lemon juice, and tamari until smooth and uniform.
In a medium pot, bring 4 cups of broth to a boil. Add whites of green onion if using here.
Add the tahini mixture and mix until incorporated into the broth.
Add your vegetables and tofu to cook through, then taste to adjust seasoning. Feel free to add more salt, pepper, or sesame oil if desired.
Divide soup between two bowls, and add your preferred garnishes!
Enjoy :)
