Cut the beef and various vegetables into bite-sized pieces.
Marinate the beef with soy sauce, minced garlic, pepper, and sugar.
Add cooking oil to a pot and stir-fry the marinated beef.
When the beef is half cooked, add vegetables such as carrots, onions, and potatoes and stir-fry together.
Pour in 150ml of water, cover with a lid, and steam over medium-low heat.
Taste and adjust seasoning if needed.
Once the vegetables and beef are tender, turn off the heat and transfer to a plate.
