Add the noodles and cook until al dente, about 6 minutes; drain. Divide the noodles, meat, and eggs between two serving bowls. Ladle in the broth. Top with the remaining scallions.

To make noodles: Place flour and salt into food processor; turn on and drizzle in water slowly just until mixture begins to combine. Knead dough for about 5 minutes, then allow to rest 30 minutes.
