A very quick and satisfying meal with lots of flavor and only a few ingredients. Serve over rice, with sesame seeds and chopped scallions on the top if you like. You can use garlic powder and powdered ginger, but fresh is better. The proportions are flexible, and you can easily add more of any sauce ingredient at the end of cooking to adjust to your taste.
In a large skillet, cook ground beef, breaking it into bits, until the meat is nearly browned. Drain most of the fat and add the fresh ginger and garlic. Continue cooking until the meat is all cooked.
Add the soy sauce, brown sugar, and red pepper flakes the ground beef and stir to combine. Cook a little longer until everything is hot and saucy.
