Some round cabbages (cut thin strips like in salad)
Some carrots (cut thin strips)
Some filament sticks
Some bean skin (photo shown below, I don't know the exact name of it but it can be found at the stalls that sell yong tau foo items. I bought it from the wet market but I kept it frozen when not in use and it could last more than a week)
As for seasoning I only use a few drops of olive oil, a few drops of sesame oil and a big tablespoon of gochujang. But you can add in more gochujang if you like your soup hot and spicy.
Put the cabbages and carrots into the pot. Add water and a few drop of olive oil. Let it boil until all the vegetables turn soft. Put in the bean skin and the gochujang. Let it boil for a while then put in the noodles, scallions and filament sticks. Let it boil for about 5 minutes and turn off the fire. Put a few drops of sesame oil over it and it is done.
