Yes you can! I like to make them up ahead of time to freeze for later. Just don't add the butter to the bread until you are ready to put them in the frying pan. Then wrap them tightly in plastic wrap or put in a zip top freezer bag and toss in the freezer. They should keep in the freezer for about 3 to 5 months. To cook, allow the sandwiches to thaw for about 20 to 30 minutes, then butter the bread and cook them in the frying pan or under the broiler, following the listed directions.
