Step 1: Heat the oil in a wok or large deep skillet over medium-high heat. Once the oil is hot, add the onion, celery, and carrot into the skillet. Stir-fry for approximately 5 minutes. Then, add the mushrooms along with the pepper and cashews. Continue to stir-fry for additional 3 minutes.

Step 2: To the skillet, pour in the wine and add the soy sauce, then cabbage. Mix well and put the lid on. Steam the cabbage for about 5 minutes until the cabbage is slightly wilted. Add the sesame oil and garlic powder. Stir well until incorporated.

Step 3: Keep stirring as the cabbage cooks. If desired, season with black pepper.
