Blend together all of your ingredients (EXCEPT the sesame seed oil, brown rice vinegar and honey) either in a food processor or blender. Pour out into a container and let sit/marinate in the refrigerator for 3 to 4 hours.
Remove the frozen noodles from the package and let sit to thaw out. This should only take an hour or so. Once the noodles are completely defrosted, separate them to ensure they do not stick together when cooking.
Prepare/slice the cucumbers and kimchi. Set aside.
Boil the noodles according to package directions; usually only 4 minutes or so. During the last minute of cooking, prepare an ice bath for the noodles. Drain the noodles and wash them thoroughly and transfer to an ice bath so the noodles stop cooking. Set aside.
Remove the bibim sauce from refrigerator and mix in (by hand) the sesame seed oil, brown rice vinegar and honey.
Combine and mix the noodles and the bibim sauce together in a big bowl. I usually wear plastic gloves and do this by hand. (Alternatively, you can serve the noodles and a dollop of bibim sauce into each bowl and have each person mix separately.)
Portion out the noodles into each serving bowl, pour in a little of the cold instant mul naeng myun soup/broth (*only if desired), top with the cucumbers and kimchi. Lightly drizzle on a touch of sesame seed oil, brown rice vinegar if desired, and top with a hard boiled egg and sprinkle on some sesame seeds. Enjoy!!
