Ingredients
Servings
4
- 4 Chilean sea bass fillets (6 oz each), skin on
- 2 tablespoons extra virgin olive oil
- 2 lemons (zested and juiced)
- 3 garlic cloves, minced
- 1 tablespoon fresh rosemary, finely chopped
- 1 tablespoon fresh thyme leaves
- 1 teaspoon sea salt
- ½ teaspoon freshly ground black pepper
- 1 cup quinoa, rinsed
- 2 cups low-sodium vegetable broth or water
- 1 medium red bell pepper, finely diced
- ¼ cup fresh parsley, chopped
- 2 tablespoons red onion, finely chopped
- ¼ cup toasted slivered almonds
- 1 tablespoon extra virgin olive oil (for pilaf)
- Salt and pepper to taste
Instructions
-
In a small bowl, whisk together olive oil, lemon zest, lemon juice, minced garlic, rosemary, thyme, sea salt, and black pepper to create the flavorful marinade.
-
Place the Chilean sea bass fillets in a shallow dish and pour the marinade over them. Cover and refrigerate for 15 minutes to infuse the flavors.
-
While the fish marinates, rinse quinoa thoroughly under cold water until the water runs clear.
-
In a medium saucepan, bring the vegetable broth or water to a boil. Add quinoa, reduce heat to low, cover, and simmer for 15 minutes or until the liquid is absorbed and the quinoa is fluffy.
-
Turn off the heat and let the quinoa sit covered for 5 minutes. Fluff with a fork.
-
In a skillet over medium heat, warm 1 tablespoon of olive oil. Add red onion and diced red bell pepper; sauté for 3-4 minutes until softened.
-
Stir the sautéed vegetables, chopped parsley, and toasted slivered almonds into the cooked quinoa. Season with salt and pepper to taste. Keep warm.
-
Preheat the grill to medium-high heat and lightly oil the grates to prevent sticking.
-
Remove sea bass fillets from the marinade, letting excess drip off. Grill skin-side down for 5-7 minutes until the skin is crisp and the fish is nearly cooked through.
-
Carefully flip the fillets and grill the other side for 2-3 minutes until the fish flakes easily with a fork but remains moist.
-
Plate the grilled Chilean sea bass alongside a generous serving of quinoa pilaf. Garnish with additional lemon wedges and fresh herbs if desired.
-
Serve immediately for a nutrient-dense, energizing meal ideal for post-workout recovery or any healthy eating occasion.
