Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with salt, pepper, and your favorite herbs. Optionally brush a small amount of olive oil for additional moisture.
Cook the chicken on the grill for about 6-7 minutes per side until fully cooked and it reaches an internal temperature of 165°F.
While the chicken is grilling, preheat your oven to 425°F for the broccoli.
Toss the broccoli florets in the olive oil, salt, and pepper, then spread them out evenly on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes until tender with a slight crisp on the edges.
Prepare the quinoa according to package instructions if not pre-cooked; typically, rinse and simmer in water for 15 minutes until fluffy.
To plate, serve the grilled chicken breast alongside the roasted broccoli and a portion of quinoa, ensuring a balanced distribution of flavors and nutrients.
