Shell noodles, spiral noodles and straight noodles are all boiled in water, but the difference is that the time is different. You can see that the package says XXmin, which is the time when they suggest cooking noodles. Depending on the time, the hardness of noodles can basically suit your taste. Take out the noodles and drain the water at that time.
Secondly, put the bought noodle sauce in the pot, add a little water and heat it (according to the amount of sauce). When the noodles are ready, you can stir-fry them in the sauce according to your personal preference, or you can put them on a plate and pour the sauce directly on them. If you have cheese powder, you can sprinkle a little on the sauce. The proportion of sauce and noodles depends on personal preference.
