Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with salt and pepper. Optionally, add a light drizzle of olive oil for extra moisture.
Grill the chicken for about 6-7 minutes per side, or until the internal temperature reaches 165°F.
While the chicken is grilling, prepare the quinoa according to package instructions if not pre-cooked.
Toss the broccoli with olive oil, salt, and pepper, then roast in a preheated 425°F oven for about 15 minutes until tender and slightly crispy.
In a small bowl, combine the nonfat Greek yogurt, lemon juice, minced garlic, a pinch of salt, and pepper to create a light sauce.
Plate the cooked quinoa, top with sliced grilled chicken, and arrange the roasted broccoli on the side. Drizzle the yogurt sauce over the chicken or serve it as a dip.
Enjoy your balanced and protein-packed lunch!
