Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Toss the broccoli florets with half of the olive oil, salt, and pepper on the prepared baking sheet.
Roast the broccoli for 15-20 minutes until the edges are tender and slightly charred.
While broccoli roasts, whisk together the remaining olive oil, lemon juice, and your favorite dried herbs like oregano or garlic powder.
Coat the chicken breast in the lemon-herb mixture and heat a grill pan over medium-high heat.
Grill the chicken for 6-7 minutes per side or until the internal temperature reaches 165°F.
Remove chicken from the heat and let it rest for 5 minutes before slicing into thin strips.
Place the warm, cooked quinoa in a bowl and top with the sliced chicken and roasted broccoli.
Drizzle any remaining pan juices or an extra squeeze of lemon over the bowl before serving.
