Put the noodles in hot water and cook according to instructions.
Prepare a bowl of ice cold water so that you transfer the hot noodles into the cold water when cooked. This gives the noodles a soft, chewy texture.
Mix the sauce
Mix together the Gochujang, soy sauce, sugar, garlic, vinegar, sesame oil and some toasted sesame seeds. Add the sauce to the noodles and nix together until they're evenly coated
Prepare the toppings
I recommend to prepare some toppings like boiled eggs half an hour or otherwise let them cool in cold water if you're in a hurry.
Cut the fresh vegetables as you like and optionally leave some for garnish.
