01 - Cook noodles according to package directions until tender. Drain in a colander, rinse under cold water to halt cooking, and set aside.
02 - In a small mixing bowl, whisk together soy sauce, oyster sauce, fish sauce, fresh lime juice, and sugar until the sugar dissolves. Set aside.
03 - Heat 1 tablespoon of vegetable oil in a large wok or skillet over medium-high heat. Add shrimp in a single layer and stir-fry for 2–3 minutes until pink, curled, and cooked through. Transfer to a plate and set aside.
04 - Add the remaining oil to the same wok. Toss in minced garlic and sliced chilies, stir-frying for about 30 seconds until fragrant and lightly golden.
05 - Add the sliced red bell pepper, trimmed snow peas, and most of the spring onions to the wok. Stir-fry for 2–3 minutes until the vegetables are crisp-tender but still vibrant.
06 - Return the seared shrimp to the wok. Add the drained noodles and pour the prepared sauce over everything. Toss vigorously for 2–3 minutes, ensuring noodles and shrimp are evenly coated and heated through.
07 - Transfer to serving plates while hot. Garnish generously with fresh coriander leaves, toasted sesame seeds, reserved spring onions, and lime wedges on the side.
