For the tuna salad:

  • 3 ounce pouch albacore tuna or chunk light
  • 1 tbsp mayo
  • 1 tbsp finely chopped celery
  • 1/2 tbsp finely chopped onion
  • 1/8 tsp garlic powder
  • Pinch salt

For the bread:

  • 1 1/2 tablespoons butter divided
  • 1 egg
  • 3 tablespoons almond flour
  • 1/2 teaspoon baking powder
  • 1 tbsp parmesan cheese
  • Pinch salt

For the tuna melt:

  • 1/4 cup shredded cheddar cheese


  • Preheat the oven to 400 degrees F.
  • Prepare the ingredients for the tuna salad first: mix together the pouch of tuna with the mayo, celery, onion, garlic powder, and pinch of salt.
  • Next, prepare your bread. Start by melting 1 tablespoon of the butter in a small microwave safe bowl for about 30 seconds until melted. Next, whisk in the egg. Then stir in the almond flour, baking powder, parmesan cheese, and pinch of salt.
  • Microwave the mixture for 90 seconds. Remove and let sit until it’s cool enough to handle. Slice it in half.
  • Heat a skillet over medium heat. Add the remaining 1/2 tablespoon of butter and cook each side of the bread for about 2 minutes per side, until toasted.
  • Place the bread on a baking sheet and top with the tuna salad. Add the shredded cheddar cheese on top. Bake at 400 degrees for about 5 minutes, or until the cheese is melted. Enjoy!
