Crispy thin pizza topped with seasoned hamburger, a blend of cheeses, diced tomatoes, caramelized onions and our signature sauce. 3 servings. US inspected and passed by Department of Agriculture. We revolutionized pizza when we introduced our first California Pizza Kitchen restaurant in 1985. Now, allow us to make an introduction. We're thrilled to present Limited Edition Pizzas - additions to our restaurant menu and to our selection of frozen pizzas you can enjoy at home. Our Limited Edition Cheeseburger Pizza starts with our crispy thin crust as a base. That crust is then topped with seasoned hamburger, diced tomatoes, caramelized onions, a blend of cheeses, and our signature sauce. Enjoy as is -- or get creative and add something extra on top after baking. One of our favorites is shredded lettuce lightly tossed in mayo. Limited Edition Cheeseburger Pizza is available in your grocer's freezer for a limited time only, so get it while it lasts, and see how we follow it up with our next pizza creation. Enjoy! - Rick and Larry, Co-Founders & Co-CEOs.
