Cut the cabbage and beef into bite-sized pieces.
Slice the onion and carrot as well.
Heat cooking oil in a pan and stir-fry the beef.
When the beef is halfway cooked, add onion, carrot, and cabbage, and stir-fry together.
Season with soy sauce, sugar, minced garlic, and black pepper.
Once the vegetables are softened, serve the mixture over rice to finish.
