Preheat your grill (or grill pan) to medium-high heat.
Season the chicken breast with salt, pepper, and your favorite herbs if desired.
Grill the chicken breast for about 6-7 minutes per side, or until the internal temperature reaches 165°F. Let it rest for a few minutes before slicing.
While the chicken is grilling, preheat your oven to 425°F for roasting broccoli.
Toss the broccoli with olive oil, salt, and pepper, and spread it out on a baking sheet.
Roast the broccoli in the oven for about 15-20 minutes until tender and slightly crispy on the edges.
Prepare cooked quinoa if not already done. Warm it gently if needed.
Assemble your plate by layering the quinoa, topping with slices of grilled chicken, and adding the roasted broccoli on the side.
Enjoy your balanced, nutrient-packed lunch!
