Another great way to make this casserole is to use leftover tuna. This can be prepared a day or two ahead of time and frozen before baking. Once frozen, it will need to be refrigerated for up to three months before baking. Just remember that the remaining cheese will be melted on top of the casserole while it is baking. If you'd prefer, you can also freeze this casserole in the freezer. To serve it at a party, you'll need to serve it within the hour.
