You can put just about anything on top of pizza now, and Domino’s has put two fast food classics together with pizza to come up something different — taco pizza and cheeseburger pizza. The chicken taco pizza is topped with: taco seasoning, American, cheddar and provolone cheeses, grilled chicken, onions, green peppers and diced tomatoes. The cheeseburger pizza is made with a ketchup-mustard sauce, American cheese, beef, onions, diced tomatoes, and provolone and cheddar cheeses.
