Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with your preferred spices (salt, pepper, and a squeeze of lemon work well).
Lightly brush the chicken with a portion of the olive oil.
Grill the chicken breast for about 6-7 minutes per side, or until fully cooked and juices run clear.
While the chicken is grilling, preheat your oven to 425°F to roast the broccoli.
Toss the broccoli florets with the remaining olive oil, salt, and pepper, and spread them on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes until edges become crispy.
Prepare the quinoa if not already cooked. Use 1/2 cup cooked quinoa as a base.
Plate the quinoa, top with sliced grilled chicken, and serve the roasted broccoli on the side.
Enjoy your nutritious and balanced lunch!
