Instructions

1. Step 1: In a small bowl, combine 1 tbsp paprika, 1 tsp cayenne pepper, 1 tsp garlic powder, 1 tsp onion powder, 1/2 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper. Rub this Cajun spice mix evenly over 4 catfish fillets and drizzle with 2 tbsp olive oil, coating each fillet well. Let rest for 15 minutes at room temperature.
2. Step 2: Meanwhile, in a medium bowl, mix 1 cup fresh corn kernels, 1/2 cup diced red bell pepper, 1/4 cup finely chopped red onion, 2 tbsp chopped fresh cilantro, 2 tbsp lime juice, and 1 tsp honey. Stir to combine and refrigerate until ready to serve.
3. Step 3: Preheat a grill or grill pan to medium-high heat (about 400°F). Brush the grill grates with 1 tbsp olive oil to prevent sticking.
4. Step 4: Place the catfish fillets on the grill and cook for 4-5 minutes per side, until the fish is opaque and flakes easily with a fork.
5. Step 5: Serve the grilled catfish topped with the sweet corn relish for a fresh, spicy, and tangy regional dish.
