In the meantime, heat 1 tablespoon of neutral vegetable oil in a large stock pot or Dutch oven over a medium-low flame. Add the shallot, white parts of the scallions, and the ginger, and saute until soft, about 4 minutes. Add the garlic and cook for another minute. Pour in the stock and soy sauce, and bring to a boil. Add the noodles and simmer until they are al dente, about 6 minutes, or as specified on the package. Add the meatballs and the remaining scallions to the pot. Taste for seasoning: if lacking in salt, add more soy; if you like spice, add some siracha. To serve, ladle the noodles, meatballs, and broth into 4 bowls and eat immediately.
