Green onions are a great addition to any stir fry. They add onion-y flavor without the bite of regular onions and with a beautiful herbaceous hint. In a green onion-forward dish like this one, I cut the scallions into 1-inch pieces so they have good texture and presence. In my Simple Stir-Fried Crispy Tofu and Vegetables, I slice the green onions into super thin slivers and cook them into the sauce. In my Stir-Fried Chicken and Rice Noodles, I slice them on the bias and sprinkle them on top of the finished dish for a colorful presentation.
