Preparing Moo Shu Chicken can be simple when following these clear steps:

1. Marinate Chicken: In a bowl, combine sliced chicken with soy sauce, cornstarch, and a pinch of salt. Set aside for about 10 minutes.
2. Prepare Vegetables: While the chicken is marinating, wash and cut the cabbage, mushrooms, and carrots. Chop the green onions and set aside.
3. Heat the Wok: In a large wok or skillet, heat vegetable oil over medium heat until hot.
4. Cook Chicken: Add the marinated chicken to the wok in a single layer. Stir-fry until cooked through, about 5-7 minutes.
5. Add Aromatics: Add minced garlic and ginger to the chicken, stirring for 1-2 minutes until fragrant.
6. Combine Vegetables: Toss in the cabbage, mushrooms, and carrots, stirring continuously for another 3-4 minutes until the vegetables are slightly tender.
7. Season: Pour in oyster sauce (if using) and additional soy sauce. Mix well and allow to heat through.
8. Finish: Remove from heat, and stir in chopped green onions. Adjust seasoning if necessary.
9. Warm Pancakes: In a separate skillet, warm the Chinese pancakes or tortillas over low heat until they are pliable.
10. Serve: Spoon Moo Shu Chicken onto the pancakes, roll them up, and enjoy!
