Preheat your oven to 425°F for roasting the broccoli.
Toss broccoli with a small amount of olive oil, salt, and pepper, and spread onto a baking sheet.
Roast the broccoli in the preheated oven for 15-20 minutes until tender and slightly crispy on the edges.
While the broccoli roasts, season the salmon fillet with salt and pepper.
Heat a non-stick skillet over medium-high heat and add the remaining olive oil.
Place the salmon fillet, skin-side down if applicable, in the skillet and sear for about 4 minutes.
Flip the salmon and cook for an additional 3-4 minutes, or until the fish is opaque and flakes easily.
Heat the cooked quinoa briefly in a microwave or in a pan to warm.
Plate the seared salmon alongside warm quinoa and roasted broccoli. Serve immediately.
