1. Preheat oven to 350°F.

2. Cut lemon in half and squeeze the juice from one half into a baking dish (reserve the other half for the pesto). Add the oil, garlic, salt, and pepper to the baking dish and stir to combine. Place the cod fillets in the dish, turning to coat, and allow to marinate for 15 minutes while you make the pesto.

3. Make the pesto by placing the kale, basil, garlic, spices, lemon juice, walnuts, and cheese into a food processor and process to chop. Slowly add the olive oil while continuing to pulse until pesto is a smooth consistency.

4. Spoon 2-3 tablespoons of pesto onto each fillet, then cover and bake until fish flakes easily with a fork, 15-20 minutes.

5. Serve with lemon wedges, extra pesto on the side and bread (if desired).
