Preheat your grill or grill pan over medium-high heat.
Season the chicken breast lightly with salt, pepper, and any herbs of your choice.
Grill the chicken breast for about 6-7 minutes per side, until cooked through.
Meanwhile, preheat your oven to 425°F for the broccoli.
Toss the broccoli with olive oil, salt, and pepper, then spread it evenly on a baking sheet.
Roast the broccoli in the oven for about 15 minutes, stirring halfway through, until tender and slightly crispy.
Prepare the quinoa if not already cooked by following package directions or use pre-cooked quinoa, warming it up if necessary.
Plate the grilled chicken alongside the roasted broccoli and quinoa for a balanced, protein-packed lunch.
