Notes: The rice noodles that I used were 1/4-inch wide. If yours are wider, they may take longer to cook. Though the instructions say to par-boil, I like my noodles firm, so I usually just add them directly to the dish to cook. Other noodles, such as rice vermicelli, can be substituted. You can also briefly cook the noodles separately, and then divide into bowls and ladle the soup over the top. I used 5 long green chilies (unseeded) to get the perfect amount of heat, but your chilies may have a different level of hotness. Start with 3 and then increase if necessary. Thai bird chilies can also be used.

Toss chicken with 2 teaspoons fish sauce in a small bowl; set aside. Cover rice noodles with cool water; set aside.
Heat chicken broth, lemongrass, and chilies in large pot over medium heat to simmer. Simmer 5 minutes. Add 1 tablespoon fish sauce, 2 tablespoons lime juice, sugar, and mushrooms. Simmer until mushrooms are half-cooked, about 2 minutes.
Cut stems from cilantro and add to pot. Season to taste with lime juice, chilies, fish sauce, sugar. Add chicken and gently simmer until just cooked through, about one minute. Drain noodles and add to soup. Simmer briefly until cooked through but firm. Garnish with sliced onion and handfuls of cilantro leaves.
