Preheat the grill to medium-high heat.
Season the chicken breast with a pinch of salt, black pepper, and garlic powder.
Grill the chicken breast for about 5-6 minutes per side or until the internal temperature reaches 165°F.
While the chicken cooks, preheat your oven to 425°F for roasted broccoli.
Toss the broccoli with olive oil, a pinch of salt, and pepper, then spread it evenly on a baking sheet.
Roast the broccoli in the oven for 12-15 minutes until it is tender and slightly crispy at the edges.
Prepare the quinoa ahead of time or follow package instructions to cook it until fluffy.
Assemble the plate by placing a serving of quinoa, topping it with the grilled chicken sliced into strips, and adding the roasted broccoli on the side.
Drizzle any remaining olive oil if desired, serve warm, and enjoy your nutritious lunch.
