Cook time 10 min

Total time 20 min


  • About 20-24 ounces of mahi mahi or other fish such as cod, or tilapia; sectioned into 4 individual pieces
  • 1 tablespoon smoked paprika
  • 1 teaspoon cayenne
  • 1 teaspoon chili powder
  • 1/2 teaspoon cumin
  • 1/2 teaspoon oregano
  • 1 teaspoon salt
  • 1 teaspoon pepper
  • 2 tablespoons extra- virgin olive oil or canola oil
  • 4 low-FODMAP, gluten-free buns or thick bread
  • 1-2 tomatoes, sliced

  • Combine the paprika, cayenne, chili powder, cumin, oregano, salt and pepper in a small bowl
  • Rinse and pat dry mahi mahi fillets
  • Sprinkle the spice mix evenly over each filet, rubbing it on all sides
  • In a non-stick skillet set over medium-high, heat 1 tablespoon of oil (I love cast iron)
    • Can also grill over medium-high heat

  • Flip the filets and cook for another 4 minutes
