Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with salt, pepper, and garlic powder. Drizzle a little olive oil over the chicken to prevent sticking.
Grill the chicken breast for about 6-7 minutes per side or until fully cooked and the internal temperature reaches 165°F.
While the chicken is grilling, preheat your oven to 400°F for the broccoli.
Toss the broccoli florets with a drizzle of olive oil, a pinch of salt, and pepper. Spread evenly on a baking sheet.
Roast the broccoli in the preheated oven for 15-20 minutes, until tender and slightly charred.
If quinoa is not pre-cooked, rinse 1/4 cup of dry quinoa and cook it according to package instructions to yield approximately 0.75 cup of cooked quinoa.
Once everything is ready, plate the grilled chicken with a serving of quinoa and roasted broccoli. Drizzle lemon juice over the top for a fresh finish.
Serve warm and enjoy your balanced, protein-packed lunch.
