In a large skillet over medium-high heat, cook ground beef while breaking it into small crumbles until no longer pink.
Drain any excess fat from the pan.
Add garlic and ginger to the skillet and sauté for 90 seconds until fragrant.
Pour in soy sauce, brown sugar, sesame oil, red pepper flakes, and black pepper.
Simmer the mixture for 3 minutes until the sauce coats the beef and thickens slightly.
Serve the beef over bowls of cooked jasmine rice.
Garnish with sliced green onions and sesame seeds.
