If there's a soup more traditional than chicken noodle, we don't know what it is! And it turns out that a hot bowl of this goodness really does help to relieve the symptoms of a cold -- the steam works to open blocked nasal passages while the warm broth soothes a sore throat and helps prevent dehydration.
Using a whole bird tends to give soup much more flavor, but you can prepare your batch with the meat of a precooked rotisserie chicken from the grocery store or whatever pieces of the poultry you might have on hand. Toss in the noodles during last few minutes of cooking time so they don't get mushy, or skip the pasta and add matzo balls instead. Either way, it'll be delicious.
