Instructions

Step 1: Preheat grill to medium-high heat (about 400°F). Brush 4 catfish fillets with 2 tbsp olive oil and season evenly with 2 tbsp Cajun seasoning, 1/2 tsp salt, and 1/4 tsp black pepper. Let rest for 10 minutes.
Step 2: In a medium bowl, combine 1 1/2 cups corn kernels, 1 cup quartered cherry tomatoes, 1/2 cup finely diced red bell pepper, 1/4 cup finely chopped red onion, and 2 tbsp chopped fresh cilantro. Add 2 tbsp lime juice, 1/2 tsp salt, 1/4 tsp black pepper, and 1 tbsp olive oil; mix gently until combined. Set aside to marinate.
Step 3: Place the seasoned catfish fillets on the grill and cook for 4-5 minutes per side, until the fish flakes easily with a fork and has grill marks.
Step 4: Serve each grilled catfish fillet topped with a generous spoonful of the Southern corn relish for a bright, fresh contrast.
