Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Cut the chicken breast, broccoli, red bell pepper, and red onion into uniform, bite-sized pieces.
In a large bowl, toss the chicken and vegetables with the extra virgin olive oil, garlic powder, onion powder, ground turmeric, and black pepper until evenly coated.
Spread the chicken and vegetable mixture in a single layer on the prepared baking sheet and roast for 18 to 20 minutes, or until the chicken is cooked through.
While the vegetables roast, combine the dry quinoa and water in a small saucepan and bring to a boil.
Reduce the heat to low, cover, and simmer the quinoa for 12 to 15 minutes until the water is absorbed.
Remove the quinoa from the heat and let it sit covered for 5 minutes, then fluff with a fork.
Stir the lemon juice, lemon zest, fresh parsley, and fresh dill into the cooked quinoa.
Portion the lemon herb quinoa into a bowl and top with the roasted chicken and vegetables.
