Flaky Sausage Foldovers can be assembled ahead, making them a great option for holiday parties. Just follow the recipe through step 3. Freeze the foldovers on the cookie sheet until firm, then transfer to a resealable freezer plastic bag. Label with a "use by" date two months after the preparation date. To serve, remove the desired number of appetizers from the bag and bake as directed in step 4, adding about 5 minutes, until the foldovers are golden brown. Since a portion of the pizza sauce is used in the filling and the rest as a dip, purchase pizza sauce in the squeezable container, and keep it in the refrigerator.
