This is an easy tasty recipe that can be made in a skillet or in a wok, you can also add in a red bell pepper or some canned drained mushroom slices if desired. To save some time ask your butcher to sliced the meat for you into thin slices. Partially freeze the beef, it will make slicing easier. This recipe will serve 4 small servings, my DS can eat the whole thing himself! I would suggest to double the ingredients.
