I got this recipe years ago from Quick Cooking magazine. I like to add extra veggies, such as broccoli and red pepper. I usually serve it over steamed brown rice, but could also serve over lo mein noodles for a change. I usually use round steak for the meat, as it's usually more affordable than sirloin. I also use wok oil for the extra flavor but vegetable oil could also be used. If a time saver is needed, frozen stir fry veggies could also be used in place of fresh.
