Tuna salad with vegetables and no mayo

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. A lighter version of my tasty protein salad!

Ingredients

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 Make Tomato Tuna Salad without Mayo

Grab your favorite mixing bowl and add the ingredients. This is easy peasy – I swear! Here is how to make no mayo tuna salad:

  1. Grab a bowl to mix
    In a medium bowl, combine tomatoes, tuna, and cucumber.
  2. Add the seasonings
    Drizzle olive oil over the salad, season with a pinch of salt, and sprinkle the Italian seasoning over the top. Toss to combine.
  3. Serve or chill
    Serve immediately or refrigerate and enjoy cold.

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)

How to Serve this No Mayo Tuna with Tomatoes

With a tuna salad recipe this flavorful, there are so many yummy ways that it can be served. Some of my favorite serving suggestions are:

  • Add on top of Cilantro Lime Cauliflower Rice for a yummy tuna salad bowl
  • Create Easy Paleo Bread for Sandwiches and make a delicious tuna salad sandwich

    You left off an ingredient from the photo/video. Is that feta or egg whites or something else?
