    • In a small bowl, mash avocado with a fork. Add the tuna, lime juice, salt and pepper. Stir until well combined.
    • Next, place the English muffin halves onto an ungreased baking sheet. Evenly portion the tuna and avocado mixture onto each English muffin half. Top each with a tomato slice and cheese.
    • Bake for 10 minutes, then broil for 2 - 3 minutes until the cheese is golden and the edges of the muffins are toasted.
    • Serve warm.

    Mash a fresh avocado and toss with the tuna, a squeeze of fresh lime, salt and pepper. Tomato Avocado Tuna Melt.

    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?
    This recipe is healthy + easy to make, and finished in a few minutes. Tomato + Avocado Tuna Melt

        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.
