Cod with Beans, Corn, and Pesto

Ingredients

• 4 6-ounce pieces cod fillet (about 1 inch thick), skin removed
• Kosher salt and pepper
• 1 tablespoon olive oil
• 1/2 pound green beans, cut in half crosswise (about 2 1/2 cups)
• 1 leek (white and light green parts only), sliced into half-moons
• 2 ears corn, kernels cut off the cob (about 1 cup)
• 2 tablespoons store-bought pesto, plus more for serving

Preparation

1. Season the cod with 1/2 teaspoon salt and 1/4 teaspoon pepper. Heat the oil in a large nonstick or cast-iron skillet over medium-high heat. Cook until the undersides are golden, 3 to 5 minutes.
   
   Flip the cod and scatter the green beans and leek around it. Add 1/4 cup water, cover, and cook until the vegetables are just tender and the fish is opaque throughout, 3 to 4 minutes.
   
   Transfer the cod to plates. Stir the corn into the green beans, cover, and cook for 1 minute. Stir in the pesto and serve with the cod and additional pesto, if desired.
