In a nonstick pan on medium, heat a little oil. Add eggs and without stirring cook until set. Sometimes I put a lid on pan and lower heat. Transfer to cutting board, let cool off and then roll into log and slice into thin strips. Set aside.
Place pork strips into a bowl, season with salt, pepper and add cornstarch, mixing well. In a clean skillet add a little more oil. Add pork and saute until lightly browned. Transfer to a plate or bowl.
If you need it add another drop of oil and add in mushrooms and ginger. Once the mushrooms have started to brown season with salt & pepper. Add cabbage (set aside about 1/2 cup to sprinkle on top), green onions, soy sauce, vinegar and pork. Cook, stirring occasionally, a few more minutes or until cabbage is wilted slightly and pork cooked through. Remove from heat and sprinkle on egg slices.
Warm your tortillas in the oven or in the microwave for about 5-10 minutes.
To assemble put some Hoisin sauce on the tortilla, add some cooked rice if you have some and a good spoonful of the moo shu pork filling. Roll and enjoy.
