Cultural Significance of Vegetarian Crab Noodle Soup

Bún Riêu is a traditional Vietnamese noodle soup that’s typically made with crab, tomatoes, and rice noodles. It’s a beloved dish, often enjoyed at family gatherings or special occasions. The vegetarian version, “Bún Riêu Chay,” is commonly served during Buddhist festivals and on vegetarian days, allowing people to enjoy the comforting flavors of the dish in a plant-based form.

Ingredient Substitutions and Variations:

Spicy Vegetarian Crab Noodle Soup: Add chili oil or fresh chili slices to the broth for an extra kick of heat.
