Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Rinse the dry quinoa under cold water, then place it in a small saucepan with 0.5 cup of water and a pinch of salt.
Bring the quinoa to a boil, then reduce heat to low, cover, and simmer for 12-15 minutes until water is absorbed.
While quinoa cooks, place the chicken breast and broccoli florets on the prepared baking sheet.
Drizzle the chicken and broccoli with olive oil, then sprinkle evenly with turmeric, garlic powder, sea salt, and black pepper.
Roast in the oven for 18-22 minutes, or until the chicken reaches an internal temperature of 165°F and the broccoli is slightly charred.
Remove from the oven and let the chicken rest for 5 minutes before slicing into strips.
Fluff the cooked quinoa with a fork and stir in the fresh lemon juice.
Plate the lemon quinoa and top with the sliced golden chicken and roasted broccoli florets.
