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 breast for about 6-7 minutes per side until it reaches an internal temperature of 165°F.
While the chicken is grilling, preheat your oven to 425°F for the broccoli.
Toss the chopped broccoli with olive oil, salt, and pepper on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes or until tender and slightly caramelized.
Prepare quinoa according to package instructions if not already cooked.
To serve, layer the quinoa on a plate, slice the grilled chicken breast and place over the quinoa, and top with the roasted broccoli.
Enjoy your balanced, nutritious lunch!
