This Tuna Stuffed Avocado is a recipe I created with the tuna packed in olive oil that I’ve been infatuated with for so long. And if it’s HOT right now where you live, I think this is perfect for a no-cook low-carb dinner. Of course, there’s evidence on the blog of how I love the combination of tuna, avocado, cilantro, and lime. But if you don’t like cilantro I’d just leave that out for this tasty tuna stuffed avocado recipe.

I updated the photos for this very old recipe, and I also updated the recipe to make it a bit easier. The old recipe peeled the avocado and then scooped most of it out, leaving a “shell” of avocado to stuff with tuna. But when I made this again (a few times to get it just right) it seemed unnecessarily difficult to me to handle the peeled avocado. So the new recipe uses the avocado skin as a vessel to hold the tasty tuna, avocado, cilantro, lime, and red onion mixture.

I recommend serving this with lime wedges so you can add a generous squeeze of lime at the table. I thought one large avocado and one can of tuna was enough for a light lunch or dinner for two people, but I’ll give you some side dish recommendations below. And if you’re dying from the heat, I hope this no-cook recipe can help!

What canned tuna did I use to stuff the avocado?
