Prep the vegetables by shredding half a head of cabbage, chopping one medium onion, and mincing a few cloves of garlic.

In a large skillet over medium-high heat, cook 1 pound of ground beef for 5-7 minutes until browned, breaking it apart with a spatula.

Add the chopped onion and minced garlic to the skillet. Sauté for 2-3 minutes until the onion becomes translucent and fragrant.

Now, add the shredded cabbage to the skillet and sauté for about 3-5 minutes until it starts to wilt but retains some crunch.

Reduce heat to medium and add soy sauce, oyster sauce (if using), ginger, black pepper, and salt. Stir for 1-2 minutes to coat ingredients.

Cover the skillet and let it simmer for another 5 minutes, stirring occasionally to prevent sticking.

Remove from heat and garnish with chopped green onions and sesame seeds. Serve warm.
