Vegetarian hot dog
（重定向自Veggie dog）
A vegetarian hot dog is a hot dog produced completely from non-meat products.
Vegetarian hot dogs are sometimes eaten by non-vegetarians because they are low or non-fat, have less calories, and contain no cholesterol, and little to no saturated fat, compared to hot dogs from animal meats. Therefore, they are preferred by people following a low calorie, low fat or low cholesterol diet. Unlike traditional home-made meat sausages, the casing is not made of intestine, but of plant based ingredients. Vegetarian hot dogs are usually based on some sort of soy protein. Some contain egg whites, which would make them unacceptable to vegans.
