Preheat your grill to medium-high heat and preheat the oven to 400°F for roasting the broccoli.
Season the chicken breast lightly with salt, pepper, and your favorite herbs.
Grill the chicken breast for about 6-7 minutes per side, or until fully cooked and juices run clear.
While the chicken is grilling, toss the chopped broccoli with olive oil, salt, and pepper, and spread evenly on a baking sheet.
Roast the broccoli in the preheated oven for about 15-20 minutes until tender and slightly crispy at the edges.
Prepare the quinoa according to package directions, or simply reheat the pre-cooked quinoa.
Plate the grilled chicken, a serving of quinoa, and the roasted broccoli on the side.
Enjoy your balanced and nutrient-packed lunch!
