Heat up oil in a large skillet. Add chopped onion and minced garlic and saute until onion becomes translucent.
Add ground beef and cook over medium heat, breaking it up into bits with a wooden spoon.
Cook until done and no longer pink.
In a measuring cup, whisk together soy sauce, sugar, oil, pepper flakes, pepper and ginger. Pour sauce over the beef, stir well.
Cover the pan and let simmer over medium-low heat for 5 minutes.
Serve over rice, garnished with chopped scallions or parsley.
Notes
I like to cook the beef just pass the done point, until brown bits appear on the bottom of the pan. They add more flavor to the dish. After you add the sauce, make sure you scrape the bottom with the wooden spoon so everything is in the dish.
