Heat sesame oil in a stock pot over medium heat. Add the ginger, garlic and whites of the green onions. Cook for 60 seconds. Add the yellow onion & gochugaru and cook down for 3 minutes, stirring frequently.
Pour in the broth, soy sauce and rice vinegar. Add the kimchi relish & tofu and bring the broth to a boil. Lower heat and simmer for 5 minutes.
Meanwhile, bring a pot of water to a boil* and cook the ramen noodles. Cook until al dente and drain.
Add the kale to the broth and stir until wilted (about 1 minute). Turn off the heat.
To assemble, split the noodles between 3 bowls, ladle the broth & tofu over top and serve with carrots & sesame seeds.
*If you plan to eat this all in one sitting, you can cook the ramen noodles directly in the broth.
