3. While the quinoa cooks, preheat a grill or grill pan over medium heat.
4. Brush the mackerel fillet with olive oil and season with salt, pepper, and minced garlic.

6. Once the quinoa is cooked, fluff it with a fork and stir in lemon juice, parsley, salt, and pepper.
7. Serve the grilled mackerel over the lemon herb quinoa, garnished with additional parsley if desired.
