Ingredients

Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). In a small bowl, mix 1 tbsp chili powder, 1 tsp ground cumin, 1 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper.
  2. Step 2: Brush 4 mahi-mahi fillets (5 oz each) with 2 tbsp olive oil, then rub the spice mixture evenly over both sides.
  3. Step 3: Grill the fillets for 4-5 minutes per side, until the fish is opaque and flakes easily with a fork. Remove from heat and set aside.
  4. Step 4: In a medium bowl, combine 1 diced large mango, 1 diced large avocado, 1/4 cup finely diced red onion, 1/4 cup chopped cilantro, 1 minced small jalapeño (seeded), and juice of 1 lime. Toss gently to create the salsa.
  5. Step 5: Warm 8 small corn tortillas on the grill for 30 seconds per side until pliable and lightly charred.
  6. Step 6: Assemble the tacos by flaking grilled mahi-mahi into each tortilla and topping generously with the mango-avocado salsa, drizzling with remaining 1 tbsp olive oil if desired.

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.
