In order to make them taste better, I usually cut off 1/2 inch long of root of oil vegetable and throw thew away.
Rinse the vegetable in a bucket three times to keep them clean.
Add 40 oz of water into a pot and put the heat on heat, also add three teaspoon oil, two teaspoon salt and the little bit of chicken soup powder into the pot.
Heat the water until it is boiled. Then add the oil vegetables into the soup.
Cook 3 minutes without cover up the pot. It is ready. Please remember that is only 3 minutes, don't over cook them.
