More people in the UK are following a vegan diet, with over 500,000 Brits choosing not to eat any animal products including meat, fish, milk, cheese, eggs and honey.
Across Britain, pizza restaurants are embracing vegans by introducing vegan-cheese pizzas with a variety of vegan-friendly toppings, from "mock" meats (meat substitutes) to fresh vegetables and more.
