In a medium bowl, toss the shrimp with olive oil, smoked paprika, chili powder, cumin, cayenne, salt, and pepper until well coated. Let it marinate for at least 10 minutes to absorb the flavors.
In a large skillet over medium-high heat, add the marinated shrimp. Cook for 2-3 minutes on each side until pink and opaque. Do not overcrowd the pan; cook in batches if necessary. Remove from heat.
In serving bowls, start by layering cooked quinoa or brown rice as the base.
Next, add black beans and corn. Then, layer on the cooked shrimp. Follow with diced avocado, halved cherry tomatoes, diced red onion, and chopped cilantro.
Squeeze fresh lime juice over each bowl to add brightness and flavor.
If you like it spicy, add optional toppings like jalapeños, or drizzle with sour cream and hot sauce.
Notes
Adjust the cayenne pepper to taste for desired spiciness.
