And is it just me, or is everything on an English muffin 10 times tastier than normal? Yeah, I thought so, too.

Get back on track with this yummy tuna melt recipe.

 

Tomato + Avocado Tuna Melt

Tuna is a great ingredient for keeping your budget and your diet in check. There are endless ways to incorporate wild albacore tuna into your meal routine. This Tomato + Avoado Tuna Melt is a yummy way.

You may remember Blue Harbor Fish Co. Wild Albacore Tuna from our Thai Tuna Lettuce Wrap recipe.

Blue Harbor tuna contains three ingredients: Tuna, water, and sea salt. If you are cutting back on sodium, they also offer a no salt added option.

Blue Harbor tuna contains sustainably-caught wild Albacore tuna. What does that mean?

The fish are 100% line caught using methods to safeguard seafood supplies for the future. Click here to learn more about Blue Harbor Fish Co. products.

To make this recipe, just mash the avocado together with the tuna. Then, add a squeeze or two of fresh lime juice plus salt and pepper to taste. This tuna melt recipe comes together like a dream. All it takes is a few minutes and you’ve got yourself a delicious and better for you lunch option.

 

Tuna with fresh avocado and lime juice

 

Top each muffin half with a portion of avocado and tuna mix, top with a slice of fresh tomato, and sprinkle with cheese. That’s it.

This recipe is listed as less than 30 minutes, but it is more like 15.

Think of all the ways you can make a tuna melt with Blue Harbor Tuna:
  • Add a little chopped red onion for more color and crunch.
  • Skip the tomato and add sliced mushrooms.
  • Save a few more calories and swap the jack cheese for parmesan.
  • Cutting out all bread? Replace the muffin with a slice of sweet potato (this will increase your cooking time).
  • Is it just me, or does a fried egg on top of this sound amazing?

      It helps pull it all together. I was wondering if a fried egg would be good on it, too.

    I haven’t had a tuna melt since I was a teen. My tastes have changed so much over the years. I used to dislike warm mayo, which came upon me suddenly. But I’m ready to try again, especially since you used avocado! I seriously can’t wait to try your delicious tuna melt.
