Cook the noodles: Bring a large pot of salted water to a boil. Cook noodles according to package directions until just tender. Reserve 1/4 cup of the starchy pasta water, then drain well.

Make the sauce base: In a small bowl, whisk 1/4 cup soy sauce, 2 tablespoons rice vinegar, 2 tablespoons brown sugar (or honey), and 1 to 2 teaspoons chili-garlic sauce. Adjust sweetness and heat to taste.

Sauté aromatics: In a large skillet over medium heat, warm 1 tablespoon neutral oil. Add 3 minced garlic cloves and 1 tablespoon grated ginger. Cook 30 to 45 seconds, just until fragrant. Don’t brown the garlic.

Combine with noodles: Add the drained noodles to the skillet. Pour in the sauce mixture and toss with tongs until coated. If the noodles seem dry, splash in a little reserved pasta water to loosen and help the sauce cling.

Add sesame oil: Turn off the heat. Drizzle in 1 to 2 teaspoons toasted sesame oil and toss again. This keeps the sesame aroma bright and bold.

Season and finish: Taste and add more soy sauce for salt, vinegar for tang, or sugar for balance. Toss in sliced green onions and a tablespoon of toasted sesame seeds.

Optional mix-ins: Fold in cooked protein or quick-cook veggies. For raw crunch (like cucumber or carrot), add just before serving.

Serve: Enjoy warm, room temp, or chilled. Garnish with extra green onions, sesame seeds, and a light drizzle of sesame oil if you like.
