Simple Seared Ahi Tuna Tacos (GF)


Something about summer always gives me a hankering for tacos! Fish tacos, chicken tacos, shrimp tacos, and vegan tacos (thanks Deryn ;))!

Every now and then our local Save-On-Foods gets Ahi Tuna, and I definitely have to splurge and go for it. Fish like this sure isn’t cheap in the middle of the prairies, and it makes sense!

I decided to pick up some locally made corn tortilla shells – thank you El Mercado, and seasoned the fish with some homemade taco seasoning courtesy of a lovely gal pal, Keri!

This is seriously simple to make, but tacos shouldn’t be complicated. A few good flavours and you’re set! Homemade salsa takes the tacos up a notch, and some thick sliced ripe avocado for a healthy fat source rounds it all out!

I used some kale slaw tossed in lime juice to add some veggie goodness to the tacos as well! A quick sear in the pan and the Ahi was ready to be sliced and put into the warmed corn tortilla shells.

Delightful, delicious, easy-peasy dinner!

I love it when dinners take less than 20 minutes to make – because typically when I get home from work, or wherever I was… running errands, the gym… I’m starving, and I’m tempted to go raid my pantry. If I know dinner will be ready in less than 20 it reminds me to stay out of the cupboards, and drink some water till dinner is ready to go!

When I calculated out the nutritional information for these tacos I was also pleasantly surprised at how balanced they are – even ratio of carbohydrates to proteins, a nice amount of healthy fats, AND 14g of fiber!! Woot, woot!!

What’s your favorite kind of taco?

  • We do have a good few fish mongers here in Glasgow, Scotland, but I tend to do all my shopping in one go at the supermarket unless I’m wanting to treat myself in the weekends 🙂 I have seen tuna though, but it’s a bit of a luxury!
    I hope you’ve had a wonderful start to your week! I myself am recovering from a beautiful camping trip I went on over the weekend, t’was so good to be outdoors again, like – properly! 😀 x

  • Yarrr! Love the looks of this! I am just sad that tuna is soooo expensive! Will keep my eyes out for some fishy bargains though ^ ^ This looks too delicious not to try, mmm… I love making my own seasoning mixes, and they do make great wee gifts too 😀 With the only additive being love 🙂 Wait…too cheesy? Haha! I hope you’re having a lovely Summer so far missy! xx
