Start by washing and chopping your ingredients. Dice about half a head of cabbage into bite-sized pieces, slice 8-10 shiitake mushrooms, and mince 2 cloves of garlic along with a thumb-sized piece of ginger.

Heat a large skillet or wok over medium-high heat and add the ground beef. Cook for about 5-7 minutes, stirring occasionally, until the beef is browned and fully cooked.

In the same skillet with the cooked ground beef, add the minced garlic and ginger. Stir and sauté for approximately 1 minute, or until both are fragrant.

Stir in the diced cabbage and sliced shiitake mushrooms into the pan. Cook for about 3-4 minutes, stirring constantly, until the cabbage becomes tender.

In a small bowl, combine 2 tablespoons of soy sauce, 1 tablespoon of oyster sauce, and 1 teaspoon of sesame oil. Pour this mixture over the cooking beef and vegetables.

Finally, slice a few green onions to use as a fresh garnish. Serve your stir-fry hot over steamed white rice or cauliflower rice.
