In a medium size pot, fry kimchi with vegetable oil on Med High for several minutes; mixing occasionally to avoid burning.
You'll know kimchi is cooked when the scent changes from sour to savoury.
Add water, fish sauce and bring up to a boil.
Add any other vegetables or ingredients you like and bring up to a boil again.
Remove from heat.
Salt to taste.
Garnish with scallions and serve with rice or on it's own.
