Preheat your grill to medium-high heat.
Season the chicken breast with salt, pepper, and your favorite herbs or spices.
Place the chicken breast on the grill and cook for about 6-7 minutes on each side, or until the internal temperature reaches 165°F.
While the chicken is grilling, preheat your oven to 425°F for the broccoli.
Toss the broccoli with a small drizzle of olive oil, salt, and pepper, and spread it on a baking sheet.
Roast the broccoli in the preheated oven for about 15 minutes, until edges become crispy.
Prepare the quinoa as per package instructions if not already cooked.
Plate the grilled chicken with a side of roasted broccoli and serve the quinoa on the side.
Enjoy your balanced and nutritious lunch!
