Begin by preparing your ingredients for the Mongolian Cabbage with Ground Beef. Shred about 4 cups of cabbage and set it aside. Chop one medium onion, and minutely mince three cloves of garlic and a one-inch piece of fresh ginger.

In a large skillet, heat a tablespoon of sesame oil over medium heat. Once hot, add 1 pound of ground beef, using a spatula to break it apart as it cooks. Stir occasionally for about 7-10 minutes until the beef is browned.

Stir in the chopped onion, minced garlic, and ginger. Sauté for about 3-4 minutes or until the onions become translucent and fragrant.

Add the shredded cabbage to the skillet with the beef mixture. Pour in 2-3 tablespoons of soy sauce and an optional tablespoon of oyster sauce. Season with salt and black pepper to taste. Cook for an additional 5-7 minutes.

Once the cabbage is cooked to your liking, remove the skillet from the heat. Serve hot, garnishing with chopped green onions and sesame seeds if desired.
