Pad woon sen is a traditional noodles dish. It consists of silky glass noodles that are stir-fried with vegetables such as carrots and cabbage, then topped with Thai bird chili and cilantro. The noodles should be soaked before the preparation. The sauce is made with water, soy sauce, oyster sauce, fish sauce, sugar, and white pepper.

Other common ingredients used in the dish include eggs, onions, garlic, bean sprouts, spring onions, and sometimes chicken, if desired. Before serving, it’s recommended to garnish the dish with cilantro and sliced chili peppers.
