1. Prepare the Salmon: Season salmon fillets generously with salt, pepper, smoked paprika, chili powder, onion powder, garlic powder, and a squeeze of lime juice. Heat olive oil in a pan over medium-high heat and cook the seasoned salmon until it is flaky and cooked through.
2. Prepare the Mango Salsa: Dice fresh mango, tomatoes, garlic, red onions, and green onions. Combine them in a bowl and mix with a squeeze of lime juice, salt, and pepper to taste.
3. Prepare the Creamy Lime Sauce: In a small bowl, whisk together 1/4 cup mayonnaise, 1/4 cup sour cream, juice from 1/2 a lime, zest from 1/2 a lime, 2 crushed cloves of garlic, 1/4 tsp chili powder, and 1/4 tsp cayenne pepper (adjust to your spice preference). Season with salt and pepper to taste, and add a splash of water to achieve a drizzling consistency.
4. Assemble the Bowl: Cook white rice according to package directions. In individual serving bowls, layer the cooked white rice, flaky cooked salmon, sliced avocado, roasted corn, and a generous portion of mango salsa. Drizzle generously with the creamy lime sauce before serving.
