Preheat your grill or grill pan over medium-high heat.
Season the 4-ounce chicken breast with salt, pepper, and your favorite herbs or spices.
Lightly brush the chicken with a little olive oil to retain moisture and enhance flavor.
Grill the chicken breast for about 6-7 minutes per side, or until the internal temperature reaches 165°F. Once done, let it rest for a few minutes before slicing.
Meanwhile, preheat the oven to 425°F for the broccoli. Toss 1 cup of broccoli florets with a drizzle of olive oil, salt, and pepper on a baking sheet.
Roast the broccoli for 15-20 minutes until the edges are crisp and slightly charred.
Prepare quinoa if not already cooked, following package instructions. Measure about 1/3 cup of cooked quinoa for the serving.
To serve, plate the quinoa, top with sliced grilled chicken breast, and arrange the roasted broccoli alongside.
Finish with an optional light drizzle of extra olive oil or a squeeze of lemon for added brightness.
