Cut the green onion in half horizontally, remove the core, and slice thinly. Soak in water and drain to make shredded green onion. Mince the core.

Heat salad oil in a frying pan over medium heat. Add ground meat and cook until the color changes. Add minced green onion core and stir-fry until softened. Remove excess oil with a paper towel, then add the seasonings and cook until the liquid reduces.
