Preheat your oven to 400°F (200°C) and prepare a baking sheet with parchment paper.
Toss the broccoli florets with half of the olive oil, minced garlic, and a pinch of sea salt.
Spread the broccoli on the baking sheet and roast for 15-20 minutes until the edges are slightly charred and tender.
While the broccoli roasts, season the chicken breast with salt, pepper, and your favorite dried herbs like oregano or thyme.
Heat a grill pan or outdoor grill over medium-high heat and lightly coat with a tiny bit of oil if needed.
Grill the chicken for 6-7 minutes per side, or until the internal temperature reaches 165°F.
Let the chicken rest for 3 minutes before slicing it into strips.
Warm the pre-cooked quinoa in a small pan or microwave if it isn't already hot.
Assemble the bowl by placing the quinoa at the bottom, followed by the roasted broccoli and sliced grilled chicken.
Drizzle the remaining olive oil and fresh lemon juice over the entire dish before serving.
