Avocado Tuna Melts

Avocado Tuna Melt is the perfect after school snack for the kids, or simply a quick and easy lunch for the Tuna lovers among us! – Hungry now? Jump to Recipe

Tuna and avocado really is one of my all time favourite combinations, it’s literally making me weak at the knees just thinking about it. But stick it on a bagel? With some fresh tomato and cheese?? I’m done.

Avocado Tuna Melt

But in the bigger picture, the thing I truly love about working with a simple can of tuna is it’s versatility.

It’s so easy to fall into the trap of mixing up some tuna mayo, sticking it in some pasta or bread and be done with it. I mean don’t get me wrong, that’s certainly not the worst thing I’ve heard of doing, but tuna offers itself to so many other beautiful flavours.

One thing I love to do for a quick lunch is grab a couple cans of tuna and whip up an avocado tuna melt or 2… Or 4.

Because seriously it’s way too easy not to!

How to make a Tuna Avocado Melt

Avocado Tuna Melt Process Shots

1. Grab yourself a couple cans of tuna and mix in with the fillings and seasoning. Place to one side.

2. Get an avo and a couple tomatoes and slice them up. Arrange in a circular motion on a toasted bagel. Season and give a drizzle of extra virgin olive oil

3. Top with the tuna and finish with some cheddar. Because cheddar is the best cheese for a tuna melt. Pop under the grill until golden and bubbly. Finish with a sprinkle of fresh parsley and a squeeze of lemon juice!

Easy right? 10000x times better than a boring avocado and tuna sandwich!

Not just a pretty face, these avocado tuna melts are actually packed with flavour. I love a subtle punch of garlic with a nice twang from the cayenne pepper and dijon mustard. A fresh blast of parsley with a good squeeze of lemon juice, all wrapped in some creamy mayo, topped with some ooey gooey cheddar cheese. Now that’s my kinda lunch.

Avocado Tuna Melt Cheese

Could you just finely chop the tomato and avocado as well? The simple answer – yes. But I feel it’s more of a textural treat to keep them sliced. Besides, look how pretty they are!

And kids love them. A nice way to sneak in some veggies and serve a nice hearty after school treat.

In terms of the bagel, personally I love ’em, not just for their taste but also because it helps create that perfect circle of joy. However do go ahead and usual regular bread if that’s what your tastebuds are calling for!

Avocado Tuna Melt Bagel

All in all this recipe super fun, flavoursome and incredibly moreish. The recipe below will serve 4, but feel free to bulk make and double the tuna mix in preparation for your next tuna craving!
