This is one of my favourite easy meals to make, specially on a cold day or when I'm feeling under the weather. I found the recipe bellow is a good ratio for 1 person, plus leftovers, but feel free to adjust for you.
You can sprinkle in a bit of plain flour to thicken the stock, if liked. Sprinkle over the chicken when browning, then add the stock and simmer till thickened before adding the noodles.
If you have any leftovers, they make great second day meals, just store in container in the fridge. To warm up, add to pot along with water and bring to boil, once heated through sprinkle lightly with more plain flour to thicken again and enjoy.
