  • 1 tsp ground cumin
  • ½ tsp smoked paprika
  • ½ tsp chili powder
  • 2 tbsp fresh cilantro finely chopped

Remaining Ingredients

  • 8-20 oz Mahi Mahi
  • 2 tbsp olive oil extra virgin
  • 4-5 large radishes trimmed, thinly sliced
  • 3 tbsp fresh cilantro leaves chopped
  • 8 8-inch corn tortillas warmed


Blackening Instructions

  • Combine blackening ingredients in a small bowl, mix well. Set aside.

Coleslaw instructions

  • In a large bowl, combine the cabbages and chopped carrots. In a smaller bowl, whisk together the greek yogurt, apple cider vinegar, Dijon mustard, ground cumin, and lime juice. Pour this mixture over the vegetables. Season to taste with salt and pepper, then toss to combine. Set aside.

Creamy Avocado Sauce

  • Place all ingredients in a food processor. Blend until smooth and creamy. Add additional lime juice as needed to reach desired consistency. Taste, then adjust seasonings to taste. Serve immediately.

Fish instructions

  • Generously season both sides of the Mahi Mahi with the blackening seasoning, making sure to rub it in so it sticks. Carefully slice the fish into bite-sized pieces. Set aside.
  • Add olive oil to a large cast iron or other skillet over medium heat. Once heated, add the seasoned fish, cooking until fish is opaque and flaky (usually about 3-4 minutes per side). Remove from heat and set aside.

To Serve

  • Evenly divide the creamy coleslaw and blackened fish between the 8 (warmed) tortillas. Top with sliced radishes and fresh cilantro leaves. Top with creamy Avocado Sauce. Roll and enjoy!
