Follow these easy steps to create your very own Moo Shu Chicken:

1. Prepare Ingredients: Gather and slice all your ingredients. Ensure the chicken and vegetables are ready to go.
2. Heat Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.
3. Cook Chicken: Add the sliced chicken to the skillet, seasoning with salt and pepper. Cook until no longer pink, around 5-7 minutes.
4. Add Garlic and Mushrooms: Stir in the minced garlic and shiitake mushrooms, cooking for another 2-3 minutes until mushrooms are tender.
5. Add Vegetables: Add the napa cabbage, carrot, and bell pepper. Stir-fry for about 3-5 minutes until the vegetables are crisp-tender.
6. Mix Sauces: In a small bowl, combine the hoisin sauce, soy sauce, sesame oil, and rice vinegar. Pour this mixture over the chicken and vegetables, stirring to coat evenly.
7. Heat Pancakes: In a separate pan, warm the flour pancakes gently until just heated through. This will make them pliable for wrapping.
8. Assemble: Spoon the Moo Shu mixture onto each pancake and top with chopped green onions.
9. Wrap: Fold the sides of the pancake over the filling and roll it up.
10. Serve Warm: Your Moo Shu Chicken is now ready to be enjoyed!
