Preheat your grill or grill pan over medium-high heat.
Season the chicken breast lightly with salt, pepper, and your favorite herbs or spices.
Grill the chicken breast for about 5-6 minutes per side, or until fully cooked and juices run clear.
While the chicken is grilling, preheat your oven to 425°F.
Toss the broccoli florets with olive oil, salt, and pepper, and spread them in a single layer on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes until tender and slightly crispy on the edges.
Simultaneously, cook the quinoa according to package instructions. Typically, combine 1/4 cup of dry quinoa with water, bring to a boil, then simmer for 15 minutes until water is absorbed.
Plate the sliced grilled chicken breast alongside a serving of roasted broccoli and a portion of quinoa.
Serve warm and enjoy your balanced, nutritious lunch.
