Preheat your grill or grill pan over medium-high heat.
Season the chicken breast with salt, pepper, and your favorite herbs or spices.
Grill the chicken breast for 6-7 minutes per side, or until fully cooked and juices run clear.
Meanwhile, preheat the oven to 400°F. Toss broccoli with a little olive oil, salt, and pepper, then spread on a baking sheet.
Roast the broccoli in the oven for 15-20 minutes until tender and slightly charred, stirring halfway through.
Prepare quinoa according to package instructions (or use pre-cooked quinoa) and warm it up if needed.
Assemble the plate by placing the grilled chicken breast on a bed of quinoa, with roasted broccoli on the side.
Drizzle the teaspoon of olive oil over the dish to enhance flavor and moisture, then serve and enjoy.
