Slice potatoes, onion, and bell peppers into thin strips. Cut chives into similar sizes, separating the white and green parts. Slice garlic into thin pieces.

Heat a pan over low heat and add cooking oil. Sauté garlic until fragrant without browning.

Add potatoes to the pan and stir-fry. Avoid rinsing the potatoes to retain their stickiness and enhance flavor.

Add the white part of the chives and sliced onion to the pan. Stir-fry until softened.

Add the bell peppers and green part of the chives. Season with oyster sauce and mix well.
