Prepare the Mango Salsa: Begin by dicing a ripe mango, tomatoes, and red onion. Combine with chopped cilantro and lime juice. Add salt to taste and mix well. Let sit for at least 15 minutes.

Marinate the Shrimp: Whisk together olive oil, lime juice, chili powder, garlic powder, and salt. Add shrimp and coat evenly. Let marinate for 15 minutes.

Cook the Shrimp: Heat a skillet over medium-high. Add shrimp and cook for 2 minutes on each side until opaque. Remove from heat.

Prepare the Lime-Chili Sauce: Mix mayonnaise or Greek yogurt with lime juice, chili powder, and salt. Adjust thickness with water if necessary.

Assemble the Bowls: Layer rice in each bowl, followed by avocado slices, mango salsa, and grilled shrimp. Drizzle with lime-chili sauce and garnish.
