Preheat your grill or grill pan to medium-high heat.
Season the chicken breast generously with salt and pepper. Optionally, add garlic powder or your favorite dried herbs to enhance flavor.
Grill the chicken breast for about 6-7 minutes per side, or until fully cooked and the internal temperature reaches 165°F (74°C).
While the chicken is grilling, cook quinoa according to package instructions. Once cooked, fluff with a fork.
For the broccoli, preheat your oven to 425°F (220°C). Toss the broccoli with olive oil, salt, and pepper on a baking sheet and roast for about 15-20 minutes until tender and slightly crispy on the edges.
Plate the dish by placing the fluffed quinoa in the center, topping it with sliced or chopped grilled chicken, and arranging the roasted broccoli on the side.
Serve warm and enjoy your balanced, nutrient-packed lunch.
