I like to start by preparing the bell peppers. Cut them into thin strips to ensure they cook quickly and evenly. Having all your ingredients ready makes the stir fry process smooth and stress-free.
Heat a teaspoon of vegetable oil over medium-high heat in your skillet. Sauté the peppers for about 3-4 minutes until they’re just tender but still slightly crisp. Then, transfer them to a plate so they don’t overcook.
Add the remaining oil to the skillet and season the steak with salt and pepper. Increase the heat to high and cook the steak for 5-6 minutes, stirring occasionally until it develops a nice brown crust.
Once the steak is browned, add minced garlic and ginger. Stir for about 30 seconds to release their fragrance and enhance the dish’s flavor.
Return the peppers to the skillet with the steak. In a small bowl, whisk together soy sauce, sugar, cornstarch, and 1/4 cup water. Pour the sauce over the meat and vegetables. Simmer for 2-3 minutes until the sauce thickens and coats everything nicely.
