Vegan pizza is a plant-based version of traditional pizza that replaces animal products with vegan alternatives. The crust is typically made from flour, water, yeast, and salt, while the sauce is often a tomato base or pesto without cheese. Toppings on vegan pizza can include a variety of vegetables like bell peppers, mushrooms, and olives, as well as vegan cheese made from nuts or soy. This type of pizza caters to those following a vegan diet and can be enjoyed by anyone looking for a healthier or more sustainable option.
