Begin by rinsing and patting dry the shrimp. Toss with olive oil, garlic powder, onion powder, salt, and pepper. Let marinate for about 10 minutes.

Preheat your grill to medium-high heat around 400°F (200°C). Grill shrimp 2–3 minutes each side until pink and slightly charred.

In a bowl, combine diced mango, chopped red onion, minced jalapeño, chopped cilantro, and lime juice. Season with salt and pepper. Stir gently to combine.

In a small bowl, whisk together mayonnaise, Sriracha, lime juice, garlic powder, onion powder, and a pinch of salt and pepper until smooth.

To assemble, divide cooked rice into serving bowls. Top with grilled shrimp and sliced avocado. Add mango salsa and drizzle lime-chili sauce.

Garnish with additional cilantro or lime wedges and serve immediately.
