After indulging quite a bit over the holidays, we are getting back into our regular routine here and making some healthier meals! The holidays were amazing but it definitely feels so good getting back to normal.

On the agenda for lunch today are these super simple Avocado Tuna Melts! Creamy, cheesy and delicious! We love adding avocado to the traditional tuna melt. It adds an extra creamy freshness that makes this open faced sandwich so. much. better!

If you are a tuna lover, you have probably been enjoyed a tuna melt more than once in your life! If you haven’t, you need to get on that ASAP! They’ve got the perfect balance between crunchy and creamy that is so satisfying to eat!

The perfect tuna melt

Essential to a perfect tuna melt is perfectly toasted bread! No one in the history of the tuna melt has every bitten into a soggy sandwich and enjoyed it. So the first thing you need to do is toast your bread!

Then you add some much needed freshness! Fresh tomatoes and, of course, avocado are the best on tuna melts! A must in our house!

Next, you mix your tuna salad in a bowl and add that on top! I love to add fresh green onion to my tuna mix for some more fresh flavour. A good sprinkling of cheese and then under the broiler to ensure it gets super melty and delicious! That’s pretty much all it takes to achieve perfection!

I like to squeeze a teeny bit of lime juice on top before eating but my hubby prefers it without. I might be alone in this. I tend to squeeze lemon and lime on almost anything, especially fish. Maybe I’m weird.

What my hubby and I do agree on is just how freakin’ delicious Avocado Tuna Melts are! Believe me when I tell you, this is a true compliment coming from my husband who is not a huge avocado fan! The first time I made these for him, he requested I leave out the avocado for him. After coaxing him to try a bite of mine, he actually preferred it! Hope you enjoy it too! Bon appetit!
