Begin by finely chopping the green onions and gathering them in a bowl. Peel and devein the shrimp, then rinse quickly with cold water and dry with paper towels. Beat an egg in a cup or small bowl to mix the yolk and whites together.
Heat some oil in a large pot over medium-high flame. Once the oil is hot, place in the shrimp and stir-fry for 1-2 minutes until they turn a pretty pink hue. Add the ginger and garlic to the pot and keep stirring for another 30 seconds or so until fragrant. Sprinkle in some Creole seasoning and cook for one more minute.
Pour in the water along with concentrated stock mix into the pot. Bring to a boil, then reduce the heat to low and simmer for 5 minutes. Add in the Lo Mein noodles and cook until al dente (8-10 minutes).
Finally, pour in the soy sauce, chili sauce (optional), and green onions into the soup. Stir everything together well to evenly distribute the flavors. Serve your delicious soup with extra green onions and chili sauce (optional).
