Roughly chop the baby bok choy into chunks. Finely dice the green onion and set aside.
In a small saucepan, bring broth, ramen soup mix, miso paste, and mirin to a rolling boil. Add the baby bok choy and simmer about 2 minutes.
Add top ramen noodles and cook an additional 2 minutes. If you are planning to throw in a protein like tofu or chicken or some other fun toppings, this is a good time to toss it all in. Add sesame oil and soy sauce.
To serve, top ramen soup with fresh green onions. Carefully slice the jammy eggs in half. Nestle them into the hot noodles with their happy sunny sides up! Shower your soup with a sprinkling of furikake, and enjoy!
