The broth was definitely the star of this soup. It was very simple to make and the results were well worth it. The great thing is that I use the same ingredients for the broth and the actual soup.
For the Broth you will need:
4 Cups of Water
About 4 Green Onions and Chives
1 Handful of Shiitake Mushrooms
1 Chunk of Ginger (about 2 inches)
3 Cloves of Garlic
4 Tbs of Soy Sauce
A few Cilantro leaves
About 3-4 Bok Choy ends (I just chopped of the ends of the bok choy I was using for the soup)
Siracha to Taste (Optional, but I absolutely loved the kick)
Salt to Taste.

Just simply combine these ingredients into a medium sized pot and simmer for 30-45 and add siracha, salt and pepper to taste. Then use a sloted spoon to remove the ingredients from the pot. I reserved the the garlic, ginger and mushrooms and sliced them and added them back into the broth for my soup.
Now for the actual soup ingredients. I Pretty much used the same ingredients that I used for the broth except I added a few other things
For the Soup All you need is:
1 Cup of Shiitake and or Oyster Mushrooms (I love mushrooms so I used both)
About 3-4 small bunches of Baby Bok Choy (You could totally substitute the Bok Choy for and Leafy green you like)
1 Small Handful of Rice Noodles (You can use more or less)
1 Carrot Peeled and Thinly Sliced
1-2 Tbs of Chives
1-2 Tbs of Green Onion
2 Tbs Cilantro (I love Cilantro but you can reduce the amout if you like.
1 Slice of Lime

To Prepare just bring the broth up to a simmer and add rice noodles and cook for about 3-4 minutes then add in mushrooms, carrots, bok choy, chives, and green onion. Cover and let simmer for about 4-5 minutes. Add and additional salt to taste. Then pour your desired amount of soup into a bowl and squeeze a little lime juice into your soup and stir in the cilantro before serving. * I love siracha so I drizzled some in mine before eating it and it was AMAZING.
