Clean and prepare the beef and bean sprouts.
Slice the beef thinly and season with salt and pepper.
Heat cooking oil in a pan and stir-fry the beef.
When the beef is partially cooked, add the bean sprouts and stir-fry together.
Add soy sauce and minced garlic to season.
When the bean sprouts are wilted, turn off the heat and drizzle with sesame oil.
Transfer to a plate, sprinkle with sesame seeds, and finish.
