Kasseri cheese is a creamy Greek cheese that is almost similar to a very mild cheddar or mozzarella you may substitute the Kasseri cheese for mild cheddar or mozzarella if desired. A pre-baked focaccia crust will work well with this also in place of the store-bought boboli pizza crust, you can also make this on a pre-baked pizza crust. If the Kasseri cheese has sun-dried tomatoes already added into the cheese, just omit the tomatoes from the recipe. Adjust all amounts to suit taste, this is very good! recipe#65641 works well with this pizza!
