In a large soup man over medium heat add the sesame oil. Once the oil is hot add the garlic and ginger and cook for one minute. Add all of the other broth ingredients to the pan and bring to a boil. Reduce the heat and let everything simmer for 10 minutes. Add the ramen noodles and bok choy to the soup mixture and cook for another 5 minutes. If you're using the rice ramen, it doesn't take long for them to cook. Try not to overcook them. If you're using regular ramen, it will take a little longer. Once the noddles are done, divide the broth and noodles among 5 bowls. Top each bowl with the sauteed mushrooms and tofu. Also add the cabbage and green onion to the top of each bowl. Enjoy!
