Avocado Tuna Salad

Avocado tuna salad jazzes up the classic tuna salad sandwich by adding a Mexican twist trading the mayo for avocado and flavouring it with cilantro and lime.

I do love a good classic tuna salad sandwich, but when I want to make it a bit healthier, I drop the mayo and head for a healthier fat – avocado. Add in some red onion and classic Mexican flavourings like cilantro and lime, and you end up with a killer tuna salad sandwich.

How to make tuna avocado salad

Sustainability and responsible fishing are important things to me, so I start with a can of responsibly sourced tuna. 

This will usually be skipjack or albacore tuna, and you will see a label on the can that says “Pole and Line”.  You are going to pay a bit more for this, but if you want to do your part in keeping the oceans healthy then making the change to sustainably sourced tuna is a great start.

The tuna will most likely be chunked and not flaked, so I start by dumping it into a small bowl and then break it up into flakes by mashing it with the back of a fork.

Then, I’ll take another bowl and do the same with the avocado.

Dice up some red onions and cilantro, and then mix everything together in one of the bowls with a squeeze of lime and some salt.

Throw the tuna salad between a couple slices of whole wheat bread, and you’ve got an awesome sandwich that is like a hybrid of guacamole and tuna salad.
