Heat oil in a nonstick skillet over medium-high heat.
Season wings with salt and pepper and place in hot skillet.
Cook, undisturbed, until browned, crisp, and they easily release from the pan, about 5 minutes.
Flip and cook until browned, 3 to 4 minutes more.
Add ginger and garlic to the skillet and cook until fragrant, about 1 minute.
Add crushed red pepper and teriyaki sauce and stir to coat the wings.
Bring to a simmer and cook, stirring frequently, until sauce thickens and wings are coated in sauce.
Sprinkle with green onions before serving.
