In a large skillet on medium high heat, brown pork with onion until no pink remains. Use meat chopper or wooden spoon to break up meat while it cooks. Drain fat.
Add garlic, ginger, mushrooms, cabbage*, carrots, soy sauce, sesame oil, and about ¼ cup of chives. Cook 5 minutes, or until cabbage is cooked through.
Garnish with remaining chives, cilantro, and sesame seeds if using, and serve.
Notes
* To save time, you may use a coleslaw mix which cooks quicker. In step 2, add all ingredients except coleslaw mix, and cook 2 minutes. Then add coleslaw mix and cook 3 minutes, or until cabbage is cooked through.
Add sriracha or hot sauce to taste.
Refrigerate leftovers up to 4 days, or freeze for 1 month.
