ONE POINT ADVICE - if you cannot get your hands on these noodles
Use "Barilla Capellini No. 1". While cooking them, just add 1 tbsp of baking soda in the boiling water (1 tbsp baking soda per 1 liter of water). The pasta will turn more Ramen-like, and that's all you need to do. It is quite helpful when you are busy :-)
For the topping idea, chicken, beef, ham, onsen tamago, vegetable etc...
1. In a cooking pot, heat 1/2 tbsp oil and fry the garlic until fragrant. Add the water and bring it to a boil. Add ingredients A to season. The soup is done.
2. Boil the noodles according to the package directions, drain them very well and divide the noodles into four serving bowl. Pour the hot soup over the noodle. Top with anything you like.
