Preheat your oven to 400°F (200°C).
Toss the broccoli florets with half of the olive oil, minced garlic, salt, and pepper on a baking sheet.
Roast the broccoli for 15-20 minutes until the edges are tender and slightly crisp.
While the broccoli roasts, season the chicken breast with lemon juice, salt, pepper, and any desired dried herbs like oregano.
Heat the remaining olive oil in a grill pan or skillet over medium-high heat.
Cook 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 into strips.
Assemble your bowl by placing the cooked quinoa at the base, then top with the roasted broccoli and sliced grilled chicken.
Garnish with a final squeeze of lemon juice and fresh herbs if available.
