In a large pan, heat the olive oil over medium-high heat. Add the green onions and ginger and cook until fragrant, about 30 seconds. Add the cooked noodles. Stir in the sauce and toss gently to combine until hot. (If you prefer crunchy noodles, continue to cook the noodles in the pan, stirring occasionally)
Transfer to a large serving bowl. Serve hot.
