Vegetarian hot dog

A vegetarian hot dog is a hot dog produced completely from non-meat products. Unlike traditional home-made meat sausages, the casing is not made of intestine, but of cellulose or other plant-based ingredients. The filling is usually based on some sort of soy protein, wheat gluten, or pea protein. Some may contain egg whites, which would make them unsuitable for a lacto-vegetarian or vegan diet.

History
The history of the vegetarian hot dog is not clear, but Worthington Foods' Veja-Link meatless wieners claim to have been the world's first vegetarian hot dogs in 1949. Since the 1980s, a number of other manufacturers have entered the vegetarian hot dog market, such as Lightlife Foods, Field Roast Grain Meat Co, and Beyond Meat. Massachusetts-based LightLife first sold its Tofu Pups in 1985. In 2000, the Chicago White Sox's Comiskey Park became the first baseball venue to sell vegetarian hot dogs during games. In 2019, Moving Mountains began selling a vegan hot dog in London. The Nathan's Famous hot dog stands in New York City began selling vegan hot dogs in 2021. The hot dog is made by Meatless Farm.

Carrot hot dogs
A carrot hot dog is a carrot cured to taste like a hot dog, then grilled and placed in a roll to resemble a traditional hot dog.
