Heat 2 tablespoons of sesame oil in a large skillet or wok over medium-high heat.

Add 1 pound of ground beef to the hot skillet and cook for 5-7 minutes, stirring until browned.

Toss in 1 large chopped onion and 3 minced garlic cloves, cooking for 3-4 minutes until onions are translucent.

Incorporate 4 cups of day-old cooked rice and stir for 2-3 minutes until heated through.

Drizzle 3 tablespoons of soy sauce over the rice mixture and mix thoroughly, cooking for another minute.

Let the rice cook for an additional 5-7 minutes, stirring occasionally to achieve a crispy texture.

Remove from heat and sprinkle with chopped green onions before serving.
