For a richer flavor, try toasting the quinoa in the dry pan for a few minutes before adding the other ingredients. This brings out a nutty aroma. Feel free to substitute other vegetables based on your preference and what's in season. Zucchini, corn, or spinach would all be delicious additions. If you prefer a milder dish, reduce the amount of giardiniera or use a mild variety. A squeeze of fresh lemon juice brightens the flavors. This quinoa dish pairs well with grilled chicken, fish, or tofu for a complete meal.
