Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
In a small bowl, combine the almond meal, dried oregano, garlic powder, sea salt, black pepper, and fresh lemon zest to create the crust mixture.
Pat the basa fillets dry with a paper towel, then lightly brush the top of each fillet with half of the olive oil.
Press the almond meal mixture firmly onto the top of the fillets to create an even, crispy coating.
Toss the asparagus spears with the remaining olive oil and a pinch of salt, then arrange them on the baking sheet alongside the fish.
Bake for 12 to 15 minutes, or until the fish is opaque and flakes easily with a fork and the almond crust is golden brown.
Drizzle the fresh lemon juice over the fish and asparagus immediately after removing from the oven.
Serve the crispy basa and roasted asparagus over the warm cooked quinoa for a complete, nutrient-dense meal.
