Chop garlic into 2-3 pieces, slice oyster mushrooms, finely chop green onion, and dice ham if using.

Heat 2 tbsp vegetable oil in a pan and sauté green onion and garlic until fragrant, ensuring they don't burn.

Add mushrooms and ham to the pan, stir-fry briefly, then add 2 tbsp soy sauce for seasoning.

Continue stir-frying until ingredients are well cooked.

Add 1.5 cups of cooked rice to the pan and mix thoroughly with the other ingredients.

Finish with a pinch of ground pepper and a sprinkle of sesame seeds, mixing well. Adjust seasoning to taste.
