01 - Cook noodles according to package instructions until al dente. Drain thoroughly, rinse under cold water to halt cooking, and set aside.
02 - In a small 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 the shrimp in a single layer and stir-fry for 2 to 3 minutes until they turn pink and are cooked through. Remove from the pan and set aside.
04 - Add the remaining tablespoon of oil to the same pan. Toss in the minced garlic and sliced chilies, stir-frying for about 30 seconds until fragrant and lightly golden.
05 - Add the sliced bell pepper, trimmed snow peas, and most of the spring onions to the pan. Stir-fry for 2 to 3 minutes until the vegetables are crisp-tender but still vibrant in color.
06 - Return the cooked shrimp to the wok, add the drained noodles, and pour the prepared sauce over everything. Toss vigorously for 2 to 3 minutes, ensuring the noodles and shrimp are evenly coated and heated through.
07 - Transfer to serving plates immediately. Top with fresh coriander leaves, toasted sesame seeds, reserved spring onions, and lime wedges on the side.
