Healthy Tuna Salad without Mayo

A healthy salad that includes tuna can still be considered tuna salad even if it has no mayo. As a matter of fact, in this recipe, it’s completely unnecessary since the tuna gets mixed in with the other ingredients.

Think of it as a nutritious chopped salad rich in protein, lycopene, fiber, and minerals from just a few ingredients that are perfect for adding more nutrition to your meals.

Ingredients for Tuna Salad with Tomatoes

Here’s the simple list of ingredients that are needed to make this tuna salad with tomatoes:

Cherry tomatoes: halve the cherry tomatoes before adding them to the salad, or you can use Roma or other tomatoes cut into smaller pieces.
Canned Tuna: use canned tuna in water rather than oil for a healthier option.
Cucumber: clean and dice into bite-sized pieces.
Olive oil: a little as a dressing, used for flavor and to combine the ingredients. You could use a balsamic vinaigrette instead.
Salt: this is optional.
Italian seasoning: just a little bit added really makes the flavor pop.

How to Store this Tuna Salad

Storing tuna salad is simple to do! Once it’s made, add a lid to the container and then store it in the fridge. (I find that the best flavor comes from letting it chill in the fridge for 1-2 hours before eating.)

As long as you store the tuna salad correctly, it should stay fresh for 2-3 days. (You may need to stir it again before serving as sometimes, the tuna releases water that can settle in the bottom of the bowl)
