Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with your favorite spices such as salt, pepper, and a squeeze of lemon if desired.
Grill the chicken for about 6-7 minutes per 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 with olive oil, salt, and pepper. Spread them evenly on a baking sheet.
Roast the broccoli in the oven for 15-20 minutes, stirring halfway through, until tender with slightly crispy edges.
Prepare the quinoa as per package instructions if not already cooked, ensuring a light and fluffy texture.
Plate the meal by arranging the cooked quinoa, topped with the sliced grilled chicken breast, and add the roasted broccoli on the side.
Serve warm and enjoy your nutritious, balanced lunch.
