Preheat your grill to medium-high heat and lightly oil the grates.
Season the chicken breast with your preferred spices, such as salt, pepper, and garlic powder.
Grill the chicken for approximately 6-7 minutes per side, or until the internal temperature reaches 165°F.
While the chicken is grilling, prepare the quinoa according to package directions, typically by simmering in water for about 15 minutes until fluffy.
Steam the broccoli until tender, about 5-7 minutes, ensuring it retains its bright green color.
Plate the chicken, quinoa, and broccoli together, and finish by drizzling a tablespoon of olive oil over the broccoli or the quinoa for added flavor.
Serve warm and enjoy your balanced, protein-packed lunch.
