Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with your preferred herbs, salt, and pepper.
Grill the chicken breast for about 6-7 minutes on each side, or until fully cooked and the internal temperature reaches 165°F.
While the chicken is grilling, preheat your oven to 400°F for roasting the broccoli.
Toss the broccoli florets lightly with a drizzle of olive oil, salt, and pepper, and spread them in a single layer on a baking sheet.
Roast the broccoli in the oven for approximately 15 minutes, until the edges are lightly browned and the texture remains crisp.
Prepare the cooked quinoa if not already done; warm it slightly if desired.
Plate the grilled chicken alongside the quinoa and roasted broccoli, and drizzle any remaining olive oil over the dish for extra flavor.
Serve immediately and enjoy your balanced, nutrient-packed lunch.
