Venison, quick and dirty stir fry

Directions:Prepare rice as directed on package and keep warm.  Slice the steak into 1/4-inch strips, cutting across the grain.  Cut the tips off the green beans.  Slice the onion into 1/4-inch disks.  Melt the margarine in a skillet and add the vegetables and the garlic powder.  Cook on medium-high heat until the onion starts to separate, then add the meat and the black pepper.  Keep stirring and adding soy sauce until the meat is done.  The beans should still be crunchy but the onion should be soft.  Serve the mixture over the rice.
