I don't know what bung means, but what it says is...
1. Place the noodles in boiling water and boil 'til somewhat firm (about 1'30"). Drain water well.
2. Place contents of soup packet in a bowl and dissolve in 270cc hot water.
3. Add boiled noodles into bowl from step 2.
4. Add green onions and red ginger.
And then it says to add whatever you like to it (pork, fresh green onions, garlic, mushrooms, sesame, etc.
