Ingredients

  • 4 brioche hamburger buns
  • 1 ¼ lb mahi mahi cut into four filets (tilapia, cod, halibut or another flakey white fish will also work) (560g)
  • ½ Tbsp olive oil (7g)
  • ½ lemon, juiced (15g)

Blackened Fish Seasoning

  • 2 tsp smoked paprika
  • 2 tsp brown sugar
  • 1 tsp garlic powder
  • 1 tsp chili powder
  • 1 tsp oregano
  • ¾ tsp kosher salt
  • ¼ tsp black pepper

Greek Yogurt Tartar Sauce

  • ¼ cup nonfat Greek yogurt (60g)
  • ¼ cup low fat mayo (60g)
  • 2 Tbsp dill pickle relish, or finely chopped pickles (30g)
  • 2 Tbsp sweet relish (30g)
  • 2 Tbsp fresh dill, chopped (5g)
  • ½ lemon, juiced (15g)

Sandwich Toppings

  • 1 large heirloom tomato, sliced (120g)
  • 8 leaves of butter lettuce (15g)
  • 1 avocado, sliced (100g)
  • pickles (optional)

Instructions

  • Pat the fish filets dry and drizzle or spray them with olive oil.
  • Combine the spices for the blackened fish seasoning in a small bowl and sprinkle the seasoning over both sides of the fish, using it all up.
  • Heat a heavy-bottomed pan or cast iron skillet over medium-high (to high) heat. Add a spritz of avocado oil and let it heat for one more minute. Add the fish and cook for two minutes. Flip and turn down to medium, cooking for another two minutes or until cooked through. Finish with a fresh squeeze of lemon.
  • Make the tartar sauce by combining all ingredients in a small bowl. Set aside.
  • Spray the inside of your buns with a little mist of olive oil spray and toast face-down in a broiler for a couple of minutes.
  • Build your sandwiches using about 3 Tbsp of tartar sauce per sandwich and all the toppings you love. We like these sandwiches with tomato, butter lettuce, avocado, and pickles. Enjoy!
