Preheat your grill to medium-high heat.
Season the chicken breast with your preferred spices such as salt, pepper, and a squeeze of lemon.
Grill the chicken for approximately 6-7 minutes per side, until fully cooked and juices run clear.
While the chicken is grilling, preheat your oven to 400°F (200°C) for the broccoli.
Toss the broccoli with a drizzle of olive oil, salt, and pepper, then spread in a single layer on a baking sheet.
Roast the broccoli in the oven for 15-20 minutes, until tender and slightly crispy at the edges.
Prepare the cooked quinoa according to package instructions if not already pre-cooked.
Plate the grilled chicken with roasted broccoli and quinoa, then drizzle any remaining olive oil over the quinoa and broccoli for extra flavor.
Serve immediately and enjoy your balanced, nutritious meal.
