Preheat your oven to 400°F and line a baking sheet with parchment paper.
Toss the broccoli florets with half of the olive oil, a pinch of sea salt, and black pepper, then spread them on the baking sheet and roast for 15-20 minutes until the edges are crisp.
Season the chicken breast with your favorite dried herbs, salt, and pepper.
Heat the remaining olive oil in a grill pan or skillet over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken and broccoli are cooking, ensure your quinoa is warm and fluffy.
In a small ramekin, whisk together the tahini and lemon juice, adding a teaspoon of warm water at a time until it reaches a smooth, pourable consistency.
Slice the grilled chicken into strips.
Assemble the bowl by placing the quinoa at the base, followed by the roasted broccoli and sliced chicken.
Drizzle the lemon-tahini sauce over the top and garnish with toasted sesame seeds for a final crunch.
