For a nuttier flavor, toast the quinoa in a dry skillet for a few minutes before cooking. Feel free to substitute other vegetables based on your preference or what's in season. Zucchini, mushrooms, or spinach would all be excellent additions. If you prefer a more pronounced lemon flavor, add a bit of lemon zest along with the juice. To make this a complete meal, consider adding grilled chicken, shrimp, or tofu.
