Preheat a grill or grill pan over medium-high heat.
Season the chicken breast with salt, pepper, and any preferred herbs or spices.
Grill the chicken for about 6-7 minutes per side or until the internal temperature reaches 165°F.
While the chicken grills, preheat your oven to 425°F and line a baking sheet with parchment paper.
Toss the broccoli with 1 teaspoon of olive oil, a pinch of salt, and pepper.
Spread the broccoli evenly on the baking sheet and roast for 15-20 minutes until tender and slightly charred.
Prepare the quinoa according to package instructions if not already cooked.
Once the chicken is done, let it rest for a few minutes before slicing.
Drizzle the remaining 0.5 teaspoon of olive oil over the roasted broccoli for extra flavor.
Plate the sliced grilled chicken alongside the quinoa and roasted broccoli. Enjoy your balanced lunch!
