Preheat your grill to medium-high heat if grilling the chicken, or preheat a skillet over medium heat if cooking indoors.
Season the chicken breast lightly with salt, pepper, and any herbs of your choice.
Grill or sear the chicken breast for about 6-7 minutes on each side or until fully cooked through with an internal temperature of 165°F.
While the chicken is cooking, prepare the quinoa following package instructions. Typically, combine quinoa with water in a 2:1 ratio, bring to a boil, then simmer until tender (about 15 minutes).
Chop broccoli into florets and toss with olive oil, salt, and pepper. Roast the broccoli in a preheated oven at 425°F for about 15 minutes until edges are slightly crispy, or alternatively, steam lightly then finish in a hot pan with olive oil for added flavor.
Plate the grilled chicken breast alongside the quinoa and roasted broccoli. Drizzle any remaining olive oil over the broccoli if desired.
Serve warm and enjoy your balanced, nutrient-packed lunch.
