Who loves P.F Changs??!! I do!! Check this recipe out!

Living in a military town, I don't get to go to P.F Chang's as much as I would like. It is about an hour away. So, when I found this recipe... I was soooo excited! I have posted a copy of their lettuce wrap recipe b4(and will again). This is their Mongolian Beef and garlic noodles!!!! I KNOW!!!!!!!! YUMMY!
I have to say that these are not my recipes. they are from Ron Douglas. I changed a few things here and there, but I will post the recipe as written...

sauce
2 teaspoons of vegetable oil
1/2 teaspoon minced peeled fresh ginger
1 tablespoon chopped garlic
3/4 packed dark brown sugar
1/2 cup soy sauce
1 lb. flank steak
1/4 cup of cornstarch
1 cup vegetable oil
2 large green onions sliced
do ahead: To make the sauce, heat the 2 teaspoons veg. oil in a med. saucepan and saute the ginger and garlic, stirring constantly. Do not let the garlic burn. Add the brown sugar, soy sauce and 1/2 cup of water. Dissolve the brown sugar by whisking vigorously. Bring the mixture to a boil and let the sauce thicken, then set it aside until ready to use. Slice the flank steak into 1/4" thick pieces. coat each piece lightly in the cornstarch and refrigerate for 10 min. Heat 1 cup veg. oil in a wok or large skillet. add the beef, working in batches, and fry until each piece is slightly golden brown. Remove to paper towels and let drain.
