Prepare the Pico de Gallo: In a bowl, combine diced tomatoes, chopped red onion, cilantro, lime juice, and salt. Mix well and set aside.
Prepare the Light Yogurt Sauce: In another bowl, whisk together Greek yogurt, lime juice, honey, salt, and pepper. Adjust the taste according to your preference. Set aside.
Blackening Seasoning: In a small bowl, mix black pepper, ground cumin, dried oregano, dried parsley, cayenne pepper, smoked paprika, ground ginger, and salt. This is your blackening seasoning.
Prepare the Mahi Mahi: Pat dry the Mahi Mahi fillets with a paper towel. Rub with butter and the blackening seasoning on one side of each fillet.
Cooking the Mahi Mahi in the Oven: Preheat the oven to 400°F (200°C). Place the seasoned Mahi Mahi fillets on a baking sheet lined with parchment paper. Bake for 12-15 minutes or until the fish is cooked through.
Warm the Tortillas: In a skillet or a separate oven-safe dish, warm the tortillas for about 20 seconds on each side.
Assemble the Tacos: Place a portion of the blackened Mahi Mahi on each tortilla. Top with shredded red and white cabbage. Spoon Pico de Gallo over the fish. Drizzle with the light yogurt sauce.
Serve: Serve the Blackened Fish Tacos immediately, garnished with extra lime wedges and cilantro if desired. Enjoy your flavorful Blackened Fish Tacos!
