. Take Rosati's, for example: an Illinois-based pizza chain known for its crispy, slightly buttery thin crust. Its frozen pizza delivers a savory tavern-style crust with exceptionally melted cheese, where the outside edges become slightly burnt for a nutty flavor while the center remains gooey. These pizzas come in cheese, pepperoni, and sausage varieties. The sausage features a generous blend of spices, parmesan cheese, and a rich flavor profile — rather than the bland, rubbery pieces of meat that sometimes plague frozen pizzas.
