Cut the cabbage and beef into bite-sized pieces.
Heat oil in a pan and stir-fry the beef.
When the beef is halfway cooked, add the cabbage and stir-fry together.
Add soy sauce, sugar, pepper, and other seasonings, then mix well.
Stir-fry until the seasonings are evenly absorbed.
Spoon the stir-fried mixture over rice to finish the rice bowl.
