Friend is vegetarian but wants to eat low-carb(under 120ish per day). what are some healthy food options for her? thank you very much for your time!

Vegetables : Vegetables are a particularly good option as they are healthy and usually low in calories

Atkins Diet maybe: A low-carb diet limits grains, starchy vegetables and fruit — and emphasizes foods high in protein and fat. Many types of low-carb diets exist. Each diet has varying restrictions on the types and amounts of carbohydrates you can eat. Not all low carb diets are healthy nor equal in value.
