I found this recipe in my mother's conglomeration of clippings and "lost" recipe's. I think this is from a home ecconomics class that my sister took in high school (it looks like her writing). I'm so glad I found this. I told my mother, I'm sure she's going to want this recipe back. This is a delicious stir fry and simple to make. I slice the beef and onions and marinate for a day or two (turning occasionally) and I double the marinade. Then, when ready to cook your meal is ready in less than 30 minutes. If you want a thicker sauce, add a little cornstarch to thicken at the end of cooking.
