- Preheat the grill to medium-high heat. In a bowl, combine shrimp, olive oil, garlic powder, paprika, salt, and black pepper. Toss to coat the shrimp evenly. 
- Thread the shrimp onto skewers, if using wooden skewers, soak them in water for 30 minutes before grilling. 
- Grill the shrimp for 2-3 minutes on each side, or until they are pink and opaque. Remove from the grill and set aside. 
- In a separate bowl, combine corn, avocado, cherry tomatoes, red onion, cilantro, and lime juice. Gently toss to mix. 
- In another small bowl, mix sour cream, lime juice, and hot sauce (if using) until smooth. 
- To assemble the bowls, divide the cooked quinoa among four bowls. Top with the avocado corn salsa and grilled shrimp. Drizzle with the creamy sauce. 
- Serve immediately and enjoy!
