Preheat the grill to medium-high heat.
Season the chicken breast lightly with salt, pepper, and your preferred herbs.
Grill the chicken for about 5-6 minutes on each side until fully cooked and nicely charred.
Meanwhile, preheat your oven to 425°F (220°C) for the broccoli.
Toss the broccoli with a little salt, pepper, and half the olive oil, then spread it on a baking sheet.
Roast the broccoli in the oven for approximately 15 minutes, until tender with a slight crisp on the edges.
Prepare the quinoa according to package instructions if not pre-cooked.
Assemble your plate with the grilled chicken, roasted broccoli, and quinoa, then drizzle the remaining olive oil evenly over the quinoa for extra flavor.
Serve warm and enjoy your balanced and nutritious lunch.
