Little Caesear's to Use Meat From Impossible Foods Sausage from the meat substitute company will be used on new pizza called the 'Impossible Supreme.' The chain will test out the pizza in three locations across the United States for a month. Little Caesear's will join thousands of restaurants and chains, such as Burger King, who use Impossible Foods. The sausage, which is plant-based, is a new item from the growing company, who recently raised $300 million. It comes as the demand for plant-based protein has grown exponentially in recent years. Since debuting in 2011, Impossible Foods has raised three-quarters of a billion dollars.
