Phat si-io

Phat si-io is a Chinese-style noodle dish originating from Thailand. The dish is often prepared and served from street stalls and consists of big noodles or vermicelli which are stir-fried with thinly sliced pork, beef, chicken, or seafood.

The dish is popular because of its fragrant aroma coming from fried soy sauce (both light and dark varieties), garlic, eggs, and Chinese broccoli, which are also included in the pan. The dish is also spelled as pad see ew, with pad meaning fried, and see ew meaning soy sauce, so the name literally means fried soy sauce.
