This low-carb walnut tuna salad recipe has just a touch of cinnamon to turn everyday tuna salad into company-quality luncheon material. While the water-packed tuna already makes for a healthy dish, the addition of the cinnamon boosts the brain-improving, diabetes-fighting, and anti-inflammatory benefits of the meal.

Toasting the walnuts adds a nice touch, but the salad is still excellent with raw walnuts as well. Without toasting, this easy salad comes together in a mere 10 minutes.

If you choose to stuff the salad into hollowed-out tomatoes or bell peppers, add another 10 minutes to the prep time. Still, just 20 minutes from start to finish? That's a tuna salad recipe you'll call a keeper.


  • 1 (6-ounce) can water-packed tuna fish, drained and flaked
  • 1 large rib celery, chopped finely
  • 1/4 cup chopped walnuts (toasted, if desired)
  • 3 tablespoons mayonnaise
  • Pinch of cinnamon
  • Salt and pepper, to taste


  1. In a medium bowl, mix together the flaked tuna fish, celery, walnuts, and mayonnaise.

  2. Add a pinch of cinnamon and salt and pepper to taste.

  3. Mix thoroughly.

  4. Cover and refrigerate until ready to serve.

Variations and Substitutions 

Experiment with any fresh herbs to add some added fresh flavor to your tuna salad. Chives, basil, and oregano make great additions to a tuna salad. Test out the flavors that best suit your palate.
