Cut cucumber into thin slices. Then julienne them into thin, match-stick pieces. Chop Kimchi into thin slices as well
Make marinade: Mix gochujang, gochugaru, soy sauce, sugar, sesame oil and sesame seeds together.
Then hard-boil an egg (optional).
Put water into a pot. Place it on a medium-high heat and bring up to boil. While you wait, fill a cup with cold water. Once the pot starts to boil, place noodles in. The pot will then start foaming to the brim. Put in a dash of the cold water - and the foam will settle back down. But it will begin to foam-up again. Pour cold water in again. Repeat this process a total of 3 times. After the third time, taste and check to see if the noodle has been fully cooked through. Drain the water and rinse noodles under cold water. Set aside and let the excess water drip off.
Take out a mixing bowl. Place in the cooked noodles, Kimchi and the spicy marinade. Mix them together.
Place in your serving bowl. Top it off with cucumbers, sliced gim and baby greens. Enjoy!
