Instructions

  1. Step 1: Preheat oven to 375°F. Arrange 4 cod fillets in a baking dish and season each with 1/2 tsp salt and 1/4 tsp black pepper. In a bowl, combine 1 1/2 cups quartered cherry tomatoes, 1/2 cup chopped kalamata olives, 2 tbsp chopped fresh basil, 2 tbsp olive oil, and 1 minced garlic clove. Spoon this relish evenly over the cod fillets.
  2. Step 2: Bake the cod for 15-18 minutes until the fish flakes easily with a fork and the tomato mixture is bubbly.
  3. Step 3: Meanwhile, heat 1 tbsp olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and sauté for 30 seconds until fragrant.
  4. Step 4: Add 1 lb trimmed green beans and 1 tsp salt to the skillet. Sauté, stirring often, for 6-8 minutes until the beans are bright green and tender-crisp.
  5. Step 5: Remove green beans from heat and stir in 1 tsp lemon zest and 1/4 tsp black pepper. Serve the baked cod topped with tomato-olive relish alongside the garlic green beans.
