Prepare the pork and the vegetables.
Combine gochujang, pepper flakes, pepper powder, soy sauce, sesame oil, sugar, corn syrup, sesame seeds, and black pepper. Mix thoroughly and set aside.
In high heat, saute garlic and pork with a bit of oil.
When the pork is 70% done, mix in the vegetables and mix thoroughly.
Add the sauce and mix thoroughly.
Stir fry for 3-4 minutes more or until the vegetables are cooked but still have crunch. Do not overcook.
To give it a grilled taste, torch the spicy pork until there are several burnt marks.
Plate and top with some more sesame seeds.
Serve with rice or noodles and enjoy!
