Bun (rice vermicelli) is served MANY ways. The vegetable are a foundation for most variations. Some variations include adding beef or pork with lemongrass, grilled pork, beef, shrimp or pork pattie, shredded pork, egg roll, shrimp or shrimp and pork paste grilled on sugar cane and many more. Que Huang brand rice vermicelli was reccomended by a local Vietnamese restaurant. I also tried Jiang Xi but they are thicker than I prefer. You want vermicelli NOT spaghetti size.
