Chock full of protein and low in carbohydrates, tuna salad can be a healthy addition to any diet as long as you keep it light on the mayo. Make a batch early in the week for convenient lunches or appetizer fillings. For best results, make sure that you properly seal the storage container to get an airtight freeze.

Transfer the tuna salad to a plastic container using a spatula. Maintain at least 1/2 inch of space at the top of the container because the tuna salad will expand in the freezer.

Top the container with the plastic lid. Make sure that the lid is secure so that the tuna won't be vulnerable to the dry air in the freezer.

Apply freezer tape around the lid to keep it in place and prevent air from entering the container.

Store the tuna salad in the freezer for up to a week.
