Canned Tuna Avocado Tacos with dressing

Canned tuna avocado tacos are one of our budget-friendly recipes on an ordinary evening. Easy, quick, healthy and delicious tuna tacos will always save your time and money. 

We adore tacos made of different fillings. Sometimes when I have more time for cooking I go for more complicated taco recipes. However, when I am exhausted but want a yummy poke bite, I open up one of my canned tuna and immediately invent the filling. Be it either spicy or sweeter, these taco recipes are always a quick meal solution in my house. These kinds of tuna tacos are very flavorful and ultra-savory. I simply adore this kind of quick snacks that are loaded with greenies, any kind of meat and the best dressing. Crunchy veggies mixed with smooth avocado and some canned tuna is sometimes all you need on a busy evening. 

My daughter adores tuna in many of my recipes. Either tuna pasta salad, avocado tuna salad or other recipes, she simply enjoys eating it.

This recipe can be an inspiration for many housewives that want a tasty dinner in no time. Also, this can be a flavorful and authentic Mexican recipe if you add chili peppers and some canned corn or black beans. This recipe is so versatile that you can experience with different ingredients and toppings. Definitely, I have made my home-made mayo as dressing. But, you can top these tuna tacos with other dressings like plain yogurt, sour cream, guacamole or other basic Mexican ingredients. I try to add chili peppers or wasabi for my husband’s taco as he simply adores hot spicy fillings.

Is tuna healthy to eat?

We all know that Tuna is a kind of fish that easily accumulates toxic mercury in their flesh as a result of the polluted waters. Doctors, or other researchers, will not advise eating too much tuna fish, however, in small portions is it not a concern. But, because it is a fatty fish it is considered a healthy fish with lots of nutrients. Everything can cause dependency or side effects if you consume it in excess. 

We adore tuna both raw or canned but try to eat it in small portions.

How to make tuna tacos

For this recipe, you will definitely need tacos, greenies, canned tuna, and some dressing. Because you can make it so differently, I will show you my super easy and quick way.

Canned tuna avocado ingredients for tacos

I make this recipe for 3 persons so I took 2 small canned tuna, 1 ripe avocado, red onion, iceberg lettuce leaves, and 3 boiled eggs. All these ingredients I mix with my hearty, but yummy home-made mayo. For note: next time I will try a new dressing, so be an eye on our blog for new dressing ideas.

To make the tacos have a stable shape in order to fill it with all the ingredients, I warm-up for 3 minutes in the oven. You can easily warm them up in your microwave. 

I take a big cutting board and cut the iceberg lettuce leaves, chop the ripe and smooth avocado, chop the onion and the boiled eggs. (I boil the eggs about 6 minutes after the water is boiling to have a hard texture inside of the egg). 

What’s next:

The most satisfying process is coming – when you have to fill your tacos with everything you have prepared. 

So, I lay some green leaves, some tuna meat, some red onions, avocado, and eggs. Pour over the dressing and serve immediately. I fill the tacos with a nice amount of the mixture as I like them to be more delicious. 

Can you store it?

These best tuna tacos can be easily stored in the fridge for a few hours. But I will not recommend to store it as you can easily sum up all the ingredients in just minutes. However, you can boil the eggs ahead one day or wash the iceberg leaves properly some hours before you serve them.

How much meat in tuna tacos

We adore tuna very much. So, this is why I try to put as much as possible in my tacos. However, it is at your discretion to use the amount you adore to have. Also just to note, I try to buy canned tuna only of the best quality, more often it is of Italian origin.  

Recipe tips

  • I try to buy tortillas made of whole-grain flour to be more dietary. You can go for the classic version.
  • Add wasabi if you want it spicier.
  • Skip the avocado if you don’t like it.
  • Dressing: wasabi mayonnaise, guacamole, sour cream, or salsa.
  • Red cabbage can be used instead of iceberg lettuce leaves.
  • Corn or black beans can be great and healthy finished for these tacos.
  • Canned or fresh tuna is optional.

These tuna avocado tacos are so good and yummy that you will likely even find more moments to prepare it. This super quick and easy recipe is healthy, fresh, crunchy and great appetizers for a keto or low diet. What I love most about this recipe, is the healthy fat from the smooth avocado and the healthy protein from tuna ideally combined and topped with one of the best dressings. Such a pleasure to eat it.
