In a skillet, brown the ground beef.
In a small bowl mix the brown sugar, soy sauce, garlic, sesame, sriracha, chili oil, ginger, and crushed pepper.
Pour the sauce over the ground beef and stir to coat the beef well until it's heated thoroughly.
Serve hot.
It's delicious over rice, cabbage, carrots, broccoli or noodles. Top with sesame seeds, slivered red cabbage, and diced green onions.
