Which ingredient is not found in the Vietnamese noodle salad?

The Vietnamese noodle salad is a light and refreshing dish that typically includes a variety of fresh vegetables, herbs, and proteins, usually served over rice noodles. It is known for its vibrant flavors and textures, often topped with crushed peanuts for added crunch, and sometimes featuring proteins like shrimp or grilled chicken.

Dairy is not a common ingredient in traditional Vietnamese cuisine, particularly in dishes like noodle salads. The use of dairy products, such as cheese or cream, is not aligned with the typical flavor profiles or ingredients you would expect in this type of salad. Instead, the focus is on fresh, raw ingredients, herbs, and savory elements that create a balance without the heaviness that dairy might introduce.

In contrast, the other options—peanuts, egg, and seafood—can all be found in different variations of Vietnamese noodle salads, whether as a garnish, a topping, or as a protein source, making dairy the unlikely candidate in this context.
