Which ingredient is used in the endive dish?

Crispy quinoa is an ingredient that adds a unique texture and nutritional profile to the endive dish. It is often used to provide crunch and a nutty flavor, complementing the bitterness of the endive. Incorporating crispy quinoa not only enhances the visual appeal of the dish with its vibrant appearance but also increases its protein content, making it more satisfying. The light, airy crunch contrasts well with the crispiness of endive, creating a balanced mouthfeel that elevates the overall dining experience.

The other options, while they may be delicious in their own right, do not serve this specific purpose in the context of the endive dish. They might be more suitable in different culinary applications or combinations.
