Instructions

  1. Step 1: Preheat grill to medium-high heat (about 400°F). Brush 4 catfish fillets with 2 tbsp olive oil and sprinkle evenly with 2 tbsp Cajun seasoning. Let rest for 10 minutes.
  2. Step 2: Toss 1 cup fresh corn kernels, 1 cup halved cherry tomatoes, and 1/2 cup diced red bell pepper with 1 tbsp olive oil, 2 tbsp lime juice, 2 tbsp chopped cilantro, 1 tsp salt, and 1/2 tsp black pepper. Set aside to marinate.
  3. Step 3: Place the catfish fillets on the preheated grill and cook for 4-5 minutes per side until the fish flakes easily with a fork and has grill marks.
  4. Step 4: Serve the grilled catfish topped with the roasted corn salsa, spooning generously to combine smoky, tangy flavors.
