Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Place the cauliflower florets on the baking sheet, drizzle with 0.5 tbsp of olive oil, and sprinkle with a pinch of sea salt and black pepper.
Toss the cauliflower to coat evenly and roast in the oven for 20-25 minutes, or until the edges are tender and caramelized.
While the cauliflower roasts, pat the cod fillets dry with a paper towel to ensure a proper sear.
In a small bowl, combine the ground turmeric, garlic powder, remaining sea salt, and black pepper.
Season both sides of the cod fillets generously with the turmeric spice blend.
Heat the remaining 1 tbsp of olive oil in a large non-stick skillet over medium-high heat.
Once the pan is hot, add the cod fillets and sear for 3-4 minutes per side, or until the fish is opaque and flakes easily with a fork.
Prepare the cooked quinoa by warming it slightly if needed.
Plate the golden cod alongside the roasted cauliflower and quinoa.
Garnish the entire dish with freshly chopped parsley and a bright squeeze of lemon juice before serving.
