Prevent noodles from sticking when leftover in fridge and sorry for the basic question but I'm a... basic cook.

I'm trying to replicate a simple meal I buy at the local shop which is fine when eating hot, but when cooling, leaving in the fridge and eating during the week, the noodles always stick together.

These are the noodles I use - and I cook it with chicken, sweet chilli sauce and other veg etc. I've read drizzling in olive oil helps but it didn't help me, so I assumed that's when cooking and not when putting into tubs to keep during the week.

I have also read that instead you should cook the noodles separate, then rinse them - now I haven't tried this yet as when cooking my noodles I add herbs/spices etc, wouldn't then rinsing wash the flavours off the noodles?

Or am I supposed to rinse first and then throw into the saucepan with the flavours from the chicken etc, and then add my flavourings?

Thanks in advance!

(I will eat the noodles cold the next day, no need to reheat).
The cooking method for the noodles you're using says:


  
  Allow 1 block of noodles per person.
  Plunge them into a pan of boiling water and simmer for 4 minutes.
  Drain well and toss in a splash of soy sauce.
  
  
  When serving as part of a stir-fry: Rinse in cold water, drain, then add to the wok, tossing all ingredients together just before serving for a spectacular stir-fry with masses of flavour.


The first part of the method i.e. cooking the noodles separately is for when you want to use them plain.

The second paragraph of the method is what would be applicable in your situation. Cook your chicken/veg with the flavorings. Rinse the noodles in cold water, drain and then add to the pan mixing everything together just before serving.

When you cook the noodles with other ingredients without rinsing the noodles first, the starch washed off the noodles causes them to stick. So Yes, you're supposed to rinse them first.
