Can vegetarian eat chips such sour cream and onion?

It depends!

* The chips themselves are usually vegetarian: Potato chips are made from potatoes, oil, and seasonings. These ingredients are all vegetarian.

* The sour cream and onion flavoring is where it gets tricky:

* Traditional sour cream and onion flavoring often contains dairy: The "sour cream" part is usually made with milk solids. If you're strictly vegetarian, this would not be suitable.

* Vegan sour cream and onion flavoring exists: Many brands offer vegan-friendly versions of their chips, which use plant-based alternatives to dairy.

To be sure, check the ingredients list! Look for phrases like "non-dairy sour cream" or "vegan sour cream" if you're avoiding dairy.
