Soak noodles according to package instructions. Meanwhile, in a large pot, combine broth, fish sauce, soy sauce, and ginger and bring to a boil. Reduce heat and simmer until ginger is fragrant, 5 to 8 minutes. Stir in chicken and rice noodles and cook until warmed through, 2 minutes. Divide soup among 6 bowls; top with scallions, cilantro, basil, tomatoes, and jalapeno. Serve with lime wedges.
