Few things are as easy to make or as tasty for lunch than a simple tuna salad sandwich. It's one of my favorite things to make when I'm too busy or occupied for more involved cooking. But porting around tuna salad when the weather is warm can be a bit of a problem.
I've been experimenting with freezing tuna salad in different ways, or rather stages of development as it were, as well as different tuna salad mixes.
