Prepare Sauce: In a small bowl, whisk together brown sugar, reduced sodium soy sauce, sesame oil, crushed red-pepper flakes, and ground ginger until well combined. Set this sauce aside.

Heat Oil and Cook Garlic: Heat 1 tablespoon of vegetable oil in a large cast iron skillet over medium-high heat. Add 3 cloves of minced garlic and sauté for about 1 minute.

Brown the Beef: Add 1 pound of ground beef to the skillet, breaking it apart as it cooks. Cook for 3-5 minutes until evenly browned.

Combine and Simmer: Pour the prepared sauce mixture into the skillet with the beef and add the chopped green onions. Stir to combine and let it simmer for an additional 2 minutes.

Serve and Garnish: Spoon the mixture over rice or your choice of grain. Garnish with extra green onions and sesame seeds before enjoying.
