This thai stir-fried noodle dish is a no-fuss option served at street-food stalls and in home kitchens. Pad woon sen means stir-fried vermicelli in thai, and the dish usually includes crisp-tender vegetables, egg, and sweet and savory sauce. It's as easy to make as tossing several fresh ingredients together for a delicious and comforting dish. Thai vermicelli is different from the thin wheat spaghetti found in italian cuisine. The noodles, commonly found in china, thailand, vietnam, and other asian cuisines, are thin pasta made from rice. The rice noodles are used in stir-fries, salads like bun, and soups. Like many thai home recipes, there are many variations to this dish. We like to add the vegetables at the end because it keeps them bright and crunchy. If you prefer your vegetables on the soft side, add them first. This is a vegetarian take on the dish, but you can easily add protein like chicken, pork, or tofu.
