3Remove the chicken, let it cool, and shred into bite-sized pieces.
4Remove the vegetables from the broth and discard.
5Add the black pepper and fish sauce to the broth. Taste and adjust seasonings as needed.

7Drain the noodles and rinse under cold water.
8Divide the noodles into bowls, top with shredded chicken, cilantro, green onion, rau ram, and fried shallots. Ladle the hot broth over the bowls and serve with lime wedges.
