Deliciously Nutritious: Elevate Your Lunch with an Avocado Tuna Salad Sandwich

Why Make Avocado Tuna Salad?

Tuna is not only a great source of omega 3 fatty acids, but it is an easy, shelf stable food to keep on hand. Tuna salad sandwiches are a tasty option but sometimes people are concerned about the fat content and its impact on heart health. You can opt for a lower saturated fat mayo (like Smart Balance) or you can try an avocado tuna salad. Avocado adds more heart healthy fat and fiber! 

What You Need:

  1. Canned tuna in water
  2. Avocado
  3. Celery
  4. Red Onion
  5. Lemon
  6. Onion Powder
  7. Garlic Powder
  8. Dried Parsley or Dill 
  9. Bread, crackers, or salad for serving

Avocado Tuna Salad Variations

You can definitely get creative with your mix ins. 

Other mix in ideas:

  • Pickles
  • Relish
  • Fresh herbs 
  • Artichoke hearts
  • Capers 
  • Cucumber
  • Bell pepper 
  • Chickpeas 

I can never time my avocados right…

If you have trouble finding the right avocado or you want to be able to enjoy avocado tuna salad without having to deal with the finicky fresh avocado, try the cups of mashed avocado instead! You can do the guacamole cups, but they also make ones that are just avocado and nothing else. You can even freeze them!
