Prepare the shrimp by tossing it in a bowl with olive oil, garlic powder, onion powder, salt, and pepper. Preheat your grill or grill pan over medium-high heat and grill the shrimp for 2-3 minutes on each side until pink and caramelized.

While the shrimp cooks, prepare the mango salsa by combining diced mango, red onion, cilantro, lime juice, and jalapeño in a bowl. Season with salt and pepper to taste and let it sit for at least 5 minutes.

Create the lime-chili sauce by whisking together mayonnaise, Sriracha, lime juice, garlic powder, onion powder, salt, and pepper in another bowl until smooth. Adjust the Sriracha to your preferred spice level.

Assemble the bowls by starting with cooked rice as the base, layering grilled shrimp on top, followed by avocado slices, mango salsa, and drizzling with lime-chili sauce.

Garnish each bowl with additional cilantro, lime wedges, and a sprinkle of chili flakes or toasted sesame seeds. Serve immediately.
