Preheat your grill to medium-high heat.
Season the chicken breast with salt, pepper, and your favorite herbs.
Grill the chicken for about 6-7 minutes on each side until fully cooked and the internal temperature reaches 165°F.
While the chicken is grilling, preheat your oven to 425°F for roasting the broccoli.
Toss the broccoli florets with olive oil, salt, and pepper, and spread them out on a baking sheet.
Roast the broccoli in the oven for about 15 minutes until tender with slightly crispy edges.
Prepare the quinoa as per package instructions if not pre-cooked, then measure 3/4 cup cooked quinoa for your serving.
Assemble your plate with the grilled chicken, quinoa, and roasted broccoli. Serve warm and enjoy!
