This sandwich will rival what you get at the drive-through. Freezing the gravy in ice-cube trays makes portioning easy.
TO FREEZE: Separately cool sandwiches and gravy to room temperature. Wrap each sandwich in plastic wrap. Place sandwiches in a large heavy-duty zip-top plastic bag; freeze. Fill ice-cube molds with gravy, 3 tablespoons per cube. Freeze until solid; transfer gravy cubes to a large heavy-duty zip-top plastic bag, and return to freezer. Store sandwiches and gravy for up to 3 months.
TO HEAT: Remove sandwiches from wrapping; wrap each in a paper towel. Microwave at HIGH 1 1⁄2 to 2 minutes or until thoroughly heated. Place gravy cube in a small microwave-safe dish. Cover and microwave at HIGH for 1 minute; stir with a whisk until smooth.
