Take a frying pan and place it on medium to high heat. Once it becomes hot enough, put in the sesame oil.
After that, add the veggies, i.e., onions, cabbage, and carrots. Stir fry the veggies until they become soft & are cooked properly. It might take 5 to 7 minutes.
When the veggies are cooked, this is the perfect time to add in the Soondae. Also, add the spicy marinade sauce you made before at this point.
Now, reduce the heat to low to medium and then stir fry everything all together in order to coat nicely with the sauce.
After 4-5 minutes, turn off the heat. Add the perilla leaves. You can also sprinkle some peril leaves powder. Give it one last stir.
Garnish the soondae bokkeum with the rest of the perilla leaves on top of it. Your soondae bokkeum recipe is ready and serve it immediately!
