1 lb flank steak, thinly sliced against the grain
¼ cup cornstarch
3 tbsp vegetable oil

½ cup water or beef broth
½ cup brown sugar
Optional: 1 tsp hoisin sauce, ½ tsp sesame oil
3–4 green onions, sliced
Toss sliced beef with cornstarch. Let sit 10 minutes.
Heat oil and fry beef in batches until crispy. Set aside.
In same pan, sauté garlic and ginger. Add soy sauce, water, sugar, and optional extras. Simmer 2–3 min.
