Preparing Shrimp and Avocado Bowls with Mango Salsa & Lime-Chili Sauce is straightforward if you follow these simple steps:

1. Prepare the Shrimp: In a bowl, combine shrimp, olive oil, chili powder, salt, and black pepper. Toss well to coat the shrimp evenly with seasonings.
2. Cook the Shrimp: Heat a skillet over medium-high heat. Add the seasoned shrimp and cook for about 2-3 minutes on each side, or until they turn pink and are cooked through. Remove from heat and set aside.
3. Make the Salsa: In a large mixing bowl, combine diced mango, red onion, bell pepper, jalapeño (if using), and cilantro. Squeeze lime juice over the mixture and stir gently to combine.
4. Prepare Avocado: Dice both avocados and gently fold them into the salsa mixture. Be careful not to mash the avocados.
5. Make the Lime-Chili Sauce: In a small bowl, mix sour cream, mayonnaise, lime juice, chili powder, and salt until smooth. Adjust seasoning to taste.
6. Assemble the Bowls: In serving bowls, layer the avocado and mango salsa mixture first. Top with the cooked shrimp for a beautiful presentation.
7. Drizzle with Sauce: Finish by drizzling the Lime-Chili Sauce over the bowls for added richness and flavor.
8. Garnish: Optionally, garnish with extra cilantro or lime wedges for visual appeal.

Following these steps will lead to a stunningly delicious bowl that balances health and taste!
