Instructions
- Step 1: In a small bowl, whisk together 3 tbsp olive oil, 2 tbsp lime juice, 1 tsp salt, and 1/2 tsp black pepper. Brush this marinade over 4 tuna steaks, coating both sides evenly. Let marinate for 15 minutes at room temperature.
- Step 2: Preheat grill to medium-high heat (about 400°F). Place the tuna steaks on the grill and cook for 3-4 minutes per side for medium-rare, or longer to desired doneness. Remove and rest for 5 minutes.
- Step 3: While the tuna rests, combine 1 cup diced ripe mango, 1 cup diced ripe avocado, 1/4 cup finely chopped red onion, 2 tbsp chopped fresh cilantro, and 1 tsp minced jalapeño in a bowl. Toss gently to combine and season with a pinch of salt.
- Step 4: Serve each grilled tuna steak topped generously with 1/4 cup of the mango and avocado salsa. Add lime wedges on the side if desired.
