Little Caesars Introduces Vegan Pepperoni to Stores Nationwide Little Caesars announced today that it will introduce a vegan pepperoni to its US menu nationwide. The third-largest pizza chain in the world will feature its first plant-based meat option on its new Planteroni pizza - a dairy-based pie topped with vegan pepperoni. The plant-based pizza topping comes from the vegan brand Field Roast Grain Co. The plant-based topping can be added to any custom pizza, but currently, Little Caesars does not offer a plant-based cheese for its pizzas. The Planeteroni pizza is also a part of the company’s Slices-N-Sticks promotion where customers can order half a Planeteroni and dairy-cheese breadstick. Customers can purchase the full-size Planteroni pizza for $8.49 at Little Caesers in Los Angeles, Detroit, Miami, San Francisco, New York City, and Portland.
