Julienne the carrot, slice the onion, and cut the green onions into long pieces. Slice the bacon into bite-sized pieces.

Heat a frying pan and add 1 tbsp of cooking oil.

Add 1 tbsp of minced garlic to the pan and sauté until fragrant.

Add the bacon to the pan and stir-fry until it releases its oil and becomes slightly crispy.

Add the sliced onion and julienned carrot to the pan and stir-fry until the onion turns translucent.

Add the bean sprouts, green onions, 1 tbsp of oyster sauce, and 2 tbsp of soy sauce to the pan.

Turn off the heat and stir-fry using the residual heat to retain the crunchiness of the bean sprouts.
