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!

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

  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 cheese and 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 cheese. Now that’s my kinda lunch.

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.

Avocado Tuna Melt Cheese

What bread to use for a Tuna Melt?

Personally I love a bagel, 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. I advice going for a thick slice in comparison to a thin, flimsy slice.

What Cheese to use for a Tuna Melt?

I recommend a sharp cheddar cheese. The cheese is one of the hero ingredients of a tuna melt so I nice strong cheddar will let it shine. But whatever you fancy, just make sure it’s a cheese with a low melting point so you get a nice cheesy tuna melt. Mozzarella also works well if you want a more subtle flavour.

What to serve with an Avocado Tuna Melt?

For me it’s always gotta be some Sweet Potato Fries. But a nice side salad will also work great ๐Ÿ™‚
