Fill a large saucepan 2/3 full of water. Bring to a boil. When the water boils, add the ramen noodles and cook 3 minutes. Drain.
Meanwhile, in a wok or large frying pan, heat the oil on high heat. Add the beef, vegetables, teriyaki sauce, garlic, ginger, and seasoning packets from ramen noodles.
Stir fry until the beef is cooked through. Add the noodles and toss to combine.
