Cut the beef brisket and vegetables into bite-sized pieces.
Heat some cooking oil in a pan and stir-fry the beef brisket.
When the beef is halfway cooked, add the prepared vegetables.
Add soy sauce, sugar, minced garlic, and other seasonings, then mix well.
Cover with a lid and cook over medium-low heat until the vegetables are tender.
Finish by adding sesame oil and sesame seeds.
