Heat half the oil in a large skillet or wok over medium-high heat. Pour in beaten eggs and cook into a flat omelette. Remove, slice into strips, and set aside.
Add remaining oil to the same pan and sear pork strips until browned and cooked through, about 3-4 minutes. Remove and set aside.
In the same pan, add cabbage, ginger, garlic, and mushrooms. Cook until tender, about 5 minutes.
Return pork and eggs to the pan with the vegetables.
In a small bowl, whisk together soy sauce, hoisin sauce, sesame oil, honey, cornstarch, salt, and pepper. Add to the pan.
Simmer until sauce thickens, about 2-3 minutes.
Remove from heat and garnish with green onions. Serve immediately in warm pancakes with extra hoisin sauce on the side.
