Preheat your oven to 425°F.
Rinse the broccoli florets and toss them with olive oil, garlic powder, salt, and pepper.
Spread the broccoli on a baking sheet and roast in the oven for 15-20 minutes until tender and slightly crispy.
While the broccoli is roasting, season the chicken breast with salt, pepper, and a pinch of garlic powder.
Grill the chicken breast over medium-high heat for about 6-7 minutes per side until fully cooked and juices run clear.
Rinse the quinoa under cold water. In a small saucepan, combine the quinoa with water (use a 1:2 ratio), bring to a boil, then reduce the heat, cover, and simmer for about 15 minutes until all the water is absorbed.
Plate the grilled chicken breast alongside a serving of quinoa and roasted broccoli, and enjoy your balanced, protein-packed lunch.
