Prep the chicken: Pat the chicken dry and slice it thinly against the grain. Toss with a pinch of salt and black pepper. Thin slices cook quickly and stay tender.

Mix the sauce: In a small bowl, whisk soy sauce, oyster sauce, dark soy (if using), brown sugar or honey, rice vinegar, sesame oil, and chili garlic sauce. Taste and adjust sweetness or heat as you like.

Cook the noodles: Boil according to package directions until just tender. Drain and set aside. If using rice noodles, rinse briefly with cool water to stop cooking.

Sear the chicken: Heat 1 tablespoon oil in a large skillet or wok over medium-high heat. Add the chicken in a single layer. Cook 3–4 minutes, stirring once or twice, until golden and cooked through. Remove to a plate.

Sauté aromatics: Add the remaining oil to the pan. Toss in minced garlic, grated ginger, and the white parts of the green onions. Cook 30–45 seconds until fragrant. Don’t brown the garlic.

Optional veggies: Add your chosen vegetables. Stir-fry 2–3 minutes until crisp-tender. Keep the heat high so they char slightly without steaming.

Bring on the sauce: Return the chicken to the pan. Pour in the sauce and bring to a simmer. Stir the cornstarch slurry and add it gradually, letting the sauce thicken until it coats the back of a spoon.

Add noodles: Toss in the cooked noodles. Use tongs to mix well so every strand gets glossy. If it seems dry, splash in a tablespoon or two of water.

Finish and garnish: Turn off the heat. Add the green onion tops and a sprinkle of sesame seeds. Taste and adjust with extra soy, vinegar, or chili for balance.

Serve hot: Plate immediately while the sauce is sticky and the noodles are bouncy.
