You can cook the wontons in the soup itself, but I prefer to cook them separately so any excess flour on the wrapper doesn't get into the soup. Set aside about 6 wontons per person. Freeze extras.
For noodles, bring soup to boil. Add noodles and cook until al dente, about 3 to 5 minutes, depending on the thickness of the noodles.
Meanwhile, in a separate pot, bring 2 liters (2 quarts) water to boil. Add wontons and simmer uncovered, stirring gently, for about 4 to 7 minutes until done. (Trick of the trade: When dumplings float to the top, that usually means they're done. Unless there is too much air inside the wontons due to bad folding.) Cut one open to check for doneness.
Divide soup and noodles into separate bowls. Add 5 to 6 wontons per bowl. Garnish with chives and serve immediately.
