Tuna Melt Tostones

If you eat paleo and you haven’t made tostones yet, you’re missing out! Even if you don’t eat paleo you’re missing out! They are extremely versatile and can give you limitless options for a round of Whole30.

Since I basically gave up eating “regular” white and wheat bread, I’ve missed tuna melts since I went grain free. I used to order tuna melts frequently at the lunch place I worked at, but these totally satisfy my cravings! The tostones have a perfect crunch to them, and they are quite sturdy.

Dietary/Lifestyle Friendly

As said above, these are both gluten and grain free! Because of the cheddar cheese melted on top, they are primal, not paleo. If you’re doing a Whole30 or strict paleo, you can omit the cheese. It will be more of an open faced tuna salad sandwich! The toppings are endless, so no food boredom here!


So many people say they’re intimidated to make tostones. My husband’s abuela makes them using a traditional “totonera”, a device made to flatten them. Check it out here. I love using mine, as it saves the parchment paper and is easier to setup and cleanup. If you don’t have one, simply use a plate and two pieces of parchment paper as the directions say. If you want step by step instructions, my instagram feed has a video post on how to make them. Just look for me @thecleanhappylife.

Tuna Salad

  • 1 apple
  • 2 celery stalks
  • 1 small onion or half a medium sized onion
  • 3 3 oz tuna
  • 1/2 cup mayonnaise


  • 4-6 green plantains
  • Coconut oil for frying

Optional toppings

  • cheese
  • chives
  • parsley
  • sesame seeds
  • red pepper flakes


Tuna Salad

  • Chop the apples, celery, and onions into small pieces. Place in a medium sized bowl.
  • Add the tuna and mayonnaise to the same bowl and mix thoroughly. Refrigerate until ready to use.


  • Heat coconut oil in a skillet on medium.
  • Peel the plantains. Slice each plantain into 3 chunks. Cut each chunk in half lengthwise.
  • Fry each chunk of plantain, about 2 -3 minutes per side, or until a light golden brown. They should NOT be cooked all the way through.
  • Remove plantains from frying pan. One at a time, place each chunk between two pieces of parchment paper. Using a plate or something flat, press down and flatten the plantain.
  • Place the flattened plantains back into the frying pan, and cook both sides for 2-3 minutes until they are crispy and golden.

Tuna Melt Tostones

  • Pre-heat the broiler on the oven. Place the rack on the top position.
  • Place the tostones onto a baking sheet. Spoon the tuna salad onto each tostone. If using cheese, place it on now.
  • Place the baking sheet under the broiler, and broil for only about 45 seconds. You want the salad heated and the cheese melted if you're using it.
  • When finished, top with any remaining optional toppings, and serve!
