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 per side or until it reaches an internal temperature of 165°F.
While the chicken is grilling, preheat your oven to 400°F for roasting the broccoli.
Toss broccoli florets with a light drizzle of olive oil, salt, and pepper, then spread them on a baking sheet.
Roast the broccoli in the preheated oven for about 15-20 minutes until tender and slightly crispy on the edges.
Meanwhile, cook quinoa according to package directions or bring to a boil in water, then simmer until water is absorbed.
Plate the grilled chicken breast, add roasted broccoli on the side, and serve with a portion of cooked quinoa.
