Vegan sausages are among the numerous plant-based meat products that are popping up in the markets. Thanks to the Impossible Burger and Beyond Burger, plant-based meat options have now become mainstream in most markets and even restaurant menus. The key ingredient in vegan sausage is typically either pea protein or soy protein, along with one or more oils (canola, coconut, sunflower), spices, and other plant-based additions.
