Cajun Catfish with Okra & Corn

Purchased Cajun or Creole seasoning flavors both the catfish and vegetables in this 30-minute dinner. This dish is best with fresh vegetables, but I were pleasantly surprised at how well it turned out with frozen okra and corn. Serve with cheese grits and a green salad.
Total Time: 30 minutes               Makes  4 servings

2             cups fresh or frozen sliced okra
1-3/4      cups fresh corn kernels (from 2 ears; see Tip), or frozen
1            medium onion, diced
2            teaspoons plus 1 tablespoon extra-virgin olive oil, divided
1-3/4     teaspoons Cajun or Creole seasoning, divided
1            pound catfish fillets, patted dry and cut into 4 portions

1 .   Preheat oven to 450°F.

2 .   Combine okra, corn, onion, 2 teaspoons oil and 3/4 teaspoon Cajun (or Creole) seasoning in a large bowl. Spread the mixture out on a large rimmed baking sheet. Roast, stirring twice, until the vegetables are tender and beginning to brown, 20 to 25 minutes.

3 .   Meanwhile, sprinkle both sides of catfish with the remaining 1 teaspoon Cajun (or Creole) seasoning. Heat the remaining 1 tablespoon oil in a large nonstick skillet over medium-high heat. Reduce heat to medium, add the fish and cook until just cooked through and starting to brown, about 4 minutes per side. Serve with the roasted vegetable
