Preheat your grill (or grill pan) to medium-high heat.
Season the chicken breast lightly with salt, pepper, and any preferred herbs.
Grill the chicken for about 5-7 minutes per side, or until the internal temperature reaches 165°F. Once cooked, let it rest for a few minutes before slicing.
While the chicken is grilling, preheat your oven to 425°F. Toss the broccoli florets in olive oil, a pinch of salt, and pepper.
Spread the broccoli evenly on a baking sheet and roast in the oven for 15-20 minutes until edges are slightly crispy.
Prepare quinoa as directed (if not already prepared), ensuring you measure out roughly 1/3 cup cooked quinoa per serving.
Plate the quinoa as the base, top with sliced grilled chicken, and add a generous serving of roasted broccoli on the side.
Enjoy this balanced, nutrient-rich lunch!
