Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with half of the olive oil and a pinch of salt, then spread them in a single layer on the baking sheet.
Roast the broccoli for 15-20 minutes until the edges are tender and slightly charred.
While the broccoli roasts, heat a small amount of olive oil in a pan over medium heat and sauté the minced garlic until fragrant.
Fold the sautéed garlic into the warm, cooked quinoa and set aside.
Pat the cod fillet dry with paper towels and season both sides with salt and black pepper.
Heat the remaining olive oil in a non-stick skillet over medium-high heat.
Place the fish in the skillet and sear for 3-4 minutes per side until the exterior is golden and the fish flakes easily with a fork.
In a small dry pan, toast the pine nuts over medium heat for 1-2 minutes until they are golden and fragrant.
Plate the garlic quinoa and top with the seared fish, then serve alongside the roasted broccoli.
Drizzle the entire plate with fresh lemon juice and sprinkle with the toasted pine nuts before serving.
