1. Preheat your oven to 200°C (400°F).
2. In a bowl, mix together olive oil, oregano, thyme, salt, and pepper.
3. Brush the mackerel fillet with the herb mixture, ensuring it is well coated.

5. Meanwhile, bring the vegetable broth to a boil in a small saucepan.
6. Once boiling, remove from heat and stir in the couscous and lemon juice. Cover and let it sit for 5 minutes.
7. Fluff the couscous with a fork and stir in chopped parsley.
8. Serve the herb-crusted mackerel on a bed of lemon couscous, garnished with additional parsley if desired.
