Preheat your grill or grill pan to medium-high heat.
Season the chicken breast lightly with salt, pepper, and your preferred herbs.
Grill the chicken for about 6-7 minutes per side until fully cooked and nicely charred.
While the chicken is grilling, preheat your oven to 425°F (220°C) for the broccoli.
Toss the broccoli florets with olive oil, salt, and pepper, then spread them on a baking sheet.
Roast the broccoli in the preheated oven for about 15 minutes or until edges are crisp and slightly browned.
Prepare the quinoa by heating it (or using pre-cooked quinoa) until warmed through.
Plate the quinoa as a base, top with the grilled chicken, and arrange the roasted broccoli on the side.
Serve immediately and enjoy your nutritious, balanced lunch.
