Step 1

Heat 1 teaspoon oil in a wide nonstick skillet over high heat until shimmering. Add mushrooms and cabbage and season lightly with salt. Cook, stirring and tossing frequently, until barely cooked through but still bright, about 3 minutes. Transfer to a medium bowl. Add 1 more teaspoon oil to wok and return to high heat until lightly smoking. Add carrot and snow peas and season lightly with salt. Cook, stirring and tossing frequently, until barely cooked through but still bright, about 3 minutes. Transfer to bowl with mushrooms and cabbage.

Step 2

Add remaining teaspoon oil and reduce heat to medium-high. Add garlic, ginger, and scallions and cook, stirring constantly until fragrant, about 15 seconds. Add noodles and toss to coat. Return vegetables to wok. Add soy sauce. Add sesame seeds and cilantro. Cook, tossing constantly, until noodles and vegetables are coated in sauce. Transfer to a plate and serve immediately.
