Set a large skillet over medium/high heat and add oil. Once hot, add ground beef and brown until no longer pink, about 5 minutes, breaking up the meat with a spatula as it’s cooked.
Season with salt and pepper.
Add onion and carrots and saute until onion is tender, 5-7 minutes, stirring occasionally. Add the garlic and cook another 30 seconds, stirring constantly.
Finally add the cabbage, ginger, soy sauce, sesame oil, and sugar. Continue sauteeing for 5-7 minutes, stirring occasionally, or until the cabbage is tender.
Serve garnished with green onion and sesame seeds if desired.
