Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a bowl, toss the broccoli florets with 1 teaspoon of 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 tender and slightly charred.
While the broccoli roasts, season the chicken breast with sea salt, black pepper, and any preferred 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.
If using pre-cooked quinoa, warm it up in a small saucepan or microwave; otherwise, ensure your quinoa is cooked according to package instructions.
Slice the grilled chicken into strips.
Assemble the bowl by placing the fluffy quinoa at the base, topped with the grilled chicken and roasted broccoli.
Drizzle the remaining 0.5 teaspoon of olive oil and the fresh lemon juice over the entire dish before serving.
