Grill the Shrimp: Toss shrimp with olive oil, garlic powder, onion powder, salt, and pepper. Grill on medium-high heat for 2–3 minutes per side, until pink and slightly charred.
Make the Mango Salsa: In a bowl, mix diced mango, red onion, jalapeño (if using), cilantro, lime juice, salt, and pepper. Stir gently and adjust seasoning to taste.
Prepare the Lime-Chili Sauce: Whisk together mayonnaise, Sriracha, lime juice, garlic powder, onion powder, salt, and pepper until smooth and creamy.
Assemble the Bowls: Start with a bed of cooked rice. Top with grilled shrimp, sliced avocado, and generous spoonfuls of mango salsa. Drizzle with the lime-chili sauce and garnish with extra cilantro or lime wedges, if desired.
