Ingredients

Instructions

  1. Step 1: Preheat grill or grill pan to medium-high heat. In a small bowl, combine 2 tbsp olive oil, 1 tsp ground cumin, 1 tsp chili powder, 1 tsp salt, and 1/2 tsp black pepper. Brush mixture over 1 lb mahi mahi fillets cut into 6 oz portions.
  2. Step 2: Grill fish for 4-5 minutes per side until opaque and easily flakes with a fork. Remove from grill and set aside.
  3. Step 3: While fish grills, warm 6 small corn tortillas on the grill or in a dry skillet for 1 minute per side until pliable.
  4. Step 4: To prepare sauce, blend 1 medium ripe avocado, 1/4 cup fresh cilantro leaves, 3 tbsp lime juice, 1/3 cup Greek yogurt, and 1 minced garlic clove until smooth and creamy.
  5. Step 5: Assemble tacos by placing grilled mahi mahi pieces on each tortilla, topping with 2 cups shredded cabbage, and drizzling with avocado cilantro sauce. Serve immediately.
