Instructions

1. Step 1: Preheat oven to 400°F. In a small bowl, combine 1 cup quartered cherry tomatoes, 1/2 cup sliced kalamata olives, 1/4 finely chopped red onion, 2 tbsp chopped fresh basil, 1 minced garlic clove, 1 tbsp lemon juice, 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Stir gently and set aside.
2. Step 2: Place 4 cod fillets in a lightly oiled baking dish and season with 1/2 tsp salt and 1/4 tsp black pepper. Drizzle with remaining 2 tbsp olive oil.
3. Step 3: Spoon the tomato-olive relish evenly over the cod fillets. Bake for 12-15 minutes, or until the fish is opaque and flakes easily with a fork.
4. Step 4: While the fish bakes, bring 1 1/4 cups vegetable broth to a boil in a small saucepan. Remove from heat, stir in 1 cup couscous, cover, and let sit for 5 minutes. Fluff with a fork and stir in 2 tbsp chopped fresh parsley.
5. Step 5: Serve the baked cod topped with relish alongside the herb couscous for a light Mediterranean meal.
