Instructions

Step 1: Pat dry 4 catfish fillets (6 oz each) and rub with 2 tbsp olive oil, 2 tbsp Cajun seasoning, 1 tsp salt, and 1/2 tsp black pepper evenly on both sides. Let rest for 10 minutes.
Step 2: Prepare the Creole tomato relish by combining 3 diced Roma tomatoes, 1 small finely chopped red bell pepper, 1/4 cup finely chopped red onion, 2 tbsp chopped fresh parsley, 1 tbsp apple cider vinegar, 1 tsp sugar, and 1 minced garlic clove in a bowl. Mix well and refrigerate for at least 15 minutes to meld flavors.
Step 3: Preheat grill to medium-high heat (about 400°F). Grill the seasoned catfish fillets for 4-5 minutes per side or until fish flakes easily with a fork and has a light char.
Step 4: Serve each grilled catfish fillet topped with 3-4 tbsp of the chilled Creole tomato relish for a fresh, tangy contrast.
