Add 2 more tablespoons of oil to the skillet and heat the oil over high heat. Add the pork; stir-fry for 1 ½ minutes. Add the garlic, mushrooms, coleslaw mix, and green onion; stir-fry for 2 more minutes. While the meat and vegetables cook, cut the eggs into thin strips. At the very end, add the chopped eggs, salt, soy sauce, hoisin sauce, sugar, sesame oil, ginger, pepper, and broth-cornstarch mixture. Cook and stir until the sauce thickens and the vegetables are tender, about 2 more minutes. Taste and season with additional salt and pepper, if necessary.
