Instructions

Step 1: Preheat your grill to medium-high heat (about 400°F). Pat dry 4 catfish fillets and brush each with 3 tbsp olive oil, then generously sprinkle 2 tbsp Cajun seasoning over both sides, pressing to adhere.
Step 2: Place the seasoned catfish fillets on the grill and cook for 4-5 minutes per side, or until the flesh is opaque and flakes easily with a fork.
Step 3: While the fish cooks, combine 1 cup fresh corn kernels, 1/2 cup finely diced red bell pepper, 1/4 cup finely diced red onion, 1/3 cup mayonnaise, 2 tbsp lime juice, and 2 tbsp chopped cilantro in a bowl. Stir until well mixed and season with salt and black pepper to taste.
Step 4: Serve the grilled catfish topped with a generous spoonful of the creamy corn relish alongside your favorite sides.
