In a large mixing bowl, combine fresh shrimp with olive oil, chili powder, cumin, garlic powder, salt, and pepper. Toss gently to coat, ensuring every shrimp is well-seasoned.

Heat a skillet over medium-high heat. Add the seasoned shrimp and cook for 2-3 minutes on each side until they turn pink and opaque.

While shrimp cooks, prepare your cooked rice. Ensure it's warmed and ready.

Start with a generous scoop of rice in each serving bowl. Layer with black beans and sweet corn, then add the cooked shrimp on top. Finish with salsa, cilantro, red onion, and avocado.

Drizzle with lime juice for an extra burst of freshness, if desired.
