For a vegetarian option, substitute vegetable broth for the chicken broth and omit the chicken. Consider adding chickpeas or white beans for added protein. To make ahead, cook the quinoa and vegetables separately and store in the refrigerator. When ready to serve, reheat the vegetables and chicken and assemble the bowls. Feel free to customize these bowls with your favorite vegetables. Spinach, kale, mushrooms, or roasted sweet potatoes would all be delicious additions.
