Ingredients

Blackened Grouper

  • 4 grouper fillets (6 ounces each)
  • 1 teaspoon paprika
  • 1 teaspoon dried thyme
  • 1 teaspoon onion powder
  • ½ teaspoon garlic powder
  • ½ teaspoon kosher salt

Mango Slaw

  • 2 tablespoons lime juice
  • 1 teaspoon honey
  • 2 ½ cups shredded red and green cabbage and carrots (can use packaged coleslaw mix)
  • 1 cup diced mango
  • teaspoon kosher salt

Lime Aioli

  • 6 tablespoons 2% Greek yogurt
  • 2 tablespoons mayonnaise
  • 1 teaspoon lime juice
  • 2 tablespoons chopped herbs like cilantro or parsley (optional)

Other:

  • 2 tablespoons olive oil
  • 4 sandwich rolls

Instructions

  • To make the mango slaw, whisk the lime juice and honey together in a bowl. Add the cabbage, carrots, mango, and salt. Toss to combine.
  • To make the lime aioli, mix the yogurt, mayonnaise, lime juice, and herbs together in a bowl.
  • To make the blackened grouper, first make a spice rub by combining the paprika, thyme, onion powder, garlic powder and salt together in a small bowl. Sprinkle both sides of the fish with the spice mix, rubbing it in. Heat the oil in a large nonstick skillet over medium heat and add the grouper. Cook 4 minutes then carefully flip the pieces over and cook another 3-4 minutes or until fish is cooked through.
  • To assemble the sandwiches, place each piece of grouper on a roll bottom and top with a dollop of lime aioli and some mango slaw. Add the roll tops and serve.

Notes

You can test to see if your fish is done is by testing it with a fork, at the thickest part, and twisting gently. The fish will flake easily when it's done. Also, when it's cooked, it will lose its translucent appearance and will be opaque.
If you can't find grouper, you can substitute any firm white fish like sea bass, mahi mahi, halibut or snapper.
You can also make smaller versions of this sandwich using slider rolls and smaller pieces of fish.  The grouper sliders make an excellent party appetizer!
