Begin by gathering all your ingredients. Chop the cabbage into bite-sized pieces and finely slice the green onions, garlic, and ginger. If you're using shiitake mushrooms, slice them thinly.

In a large skillet or wok, pour in 2 tablespoons of sesame oil and place over medium-high heat until the oil shimmers.

Add the ground beef to the hot skillet. Break it apart as it cooks, browning for about 5 minutes.

Once the beef is browned, stir in the minced garlic, ginger, and sliced shiitake mushrooms. Sauté together for 2-3 minutes.

Next, toss in the chopped cabbage along with 2-3 tablespoons of soy sauce, stirring gently and cooking for about 5-7 minutes.

Right before serving, fold in the green onions. Remove the skillet from heat.

Scoop the stir fry into bowls and serve it on its own or over steamed rice.
