Preheat oven to 400°F and line a baking sheet with parchment paper.
Pat the cod fillet dry with a paper towel to ensure the almond coating adheres properly for a crispy crust.
In a small bowl, whisk together almond flour, garlic powder, onion powder, sea salt, and black pepper.
Brush the fish with half of the olive oil, then press the almond flour mixture firmly onto the top of the fillet.
Toss asparagus with the remaining olive oil and a pinch of salt on the baking sheet, then place the fish alongside the vegetables.
Bake for 12-15 minutes until the fish is opaque and flakes easily with a fork.
While the fish bakes, stir together Greek yogurt, lemon juice, and chopped fresh dill in a small ramekin to create the sauce.
Serve the crispy fish over the warm quinoa with the roasted asparagus and a dollop of the creamy lemon-dill sauce.
