Heat half of the oil in a large skillet over medium-high heat. Add peppers and cook until crisp tender, about 4 minutes. Remove peppers from the pan and set aside.
Add remaining oil to the skillet and add steak. Cook steak in a single layer (it may take a few batches) for 5–6 minutes, or until lightly browned.
Add peppers back into the skillet with steak.
Whisk together garlic, ginger, soy sauce, sugar, cornstarch and water.
Add sauce to the skillet and bring to a simmer. Continue to simmer for 2–3 minutes, or until sauce has thickened slightly. Add additional water as needed.
