Take out a wok or large pot. Add in some neutral oil (vegetable oil). Place on medium-heat. Once the oil is hot, use your fingers and crack-in 3-4 small, dried hot red chili peppers (Peperoncino). Saute for 4-5 seconds.
Then immediately add in sliced spring onion & minced garlic pieces. Saute for 7-8 seconds (until it starts to sizzle and bubble up).
Then add in 2 teaspoons(!) of Korean gochugaru flakes. Saute for 7-8 seconds - you'll see the red chili oil form.
Then immediately add in the fresh red & green chili slices. Saute for 7-8 seconds
Then add in the fried chicken pieces. Gently toss the chicken into the chili oil, until they get evenly coated.
Now, give your sauce that you made a stir (as the sugar may have settled to the bottom). Use a spoon and place-in 7-8 large spoonfuls of sauce around the wok. (Feel free to add in more spoonfuls if you want the chicken to be more saucy & sweet).
Give the chicken a gentle toss in the sauce. You'll see that the chicken starts to turn really delicious!!
Finish by adding the green onion pieces. Give it one final stir and turn off heat.
Plate - and enjoy with your favorite beer!
