In a large skillet over medium-high heat, add avocado oil. Once hot add minced garlic, and fresh ginger (if using fresh), quickly stir and cook just until fragrant.

 Add and brown the meat until no longer pink crumbling it with a wooden spoon.

Drain excess grease, then add brown sugar, soy sauce, sesame oil, red pepper flakes, and ground ginger (if not using fresh).

Cook for few more minutes until the beef has a shiny color. Mix in chopped green onions.

Remove from heat, drizzle with more sesame oil, sesame seeds, and sprinkle with extra fresh green onions and serve over hot rice.
