Begin by boiling a large pot of water. Add the lo mein noodles and cook according to package instructions until al dente. Drain and set aside, tossing with a bit of sesame oil to prevent sticking.
In a large skillet or wok, heat the vegetable oil over medium-high heat. Add the shrimp and season with salt and pepper. Sauté for 2-3 minutes until they turn pink and are cooked through. Remove the shrimp from the skillet and set aside.
In the same skillet, add the minced garlic and grated ginger, stirring for about 30 seconds until fragrant. Then add the sliced red bell pepper and snap peas. Stir-fry for about 3-4 minutes, just until the vegetables are vibrant and slightly tender.
Return the cooked shrimp to the skillet and add the cooked lo mein noodles. Pour in the soy sauce, chili garlic sauce, and oyster sauce. Toss everything together for about 2-3 minutes, ensuring that the noodles and shrimp are evenly coated with the sauce and heated through.
Once everything is well combined, remove from heat. Serve hot, garnished with sliced green onions and a sprinkle of sesame seeds.
Notes
Adjust the chili garlic sauce to taste for desired spiciness.
