Which dish has no preservice and contains soy?

Edamame is the dish that has no preservice and contains soy. This is because edamame consists of young soybeans that are typically served steamed and lightly salted, making them a straightforward appetizer that is presented simply without any complex preparation beforehand.

In the context of the other dishes, ceviche involves marinating raw fish in citrus juices, which requires a preparation process before it is served. Calamari, which is often fried or sautéed, also undergoes a cooking process before being plated for guests. Spicy chicken is usually marinated or cooked with various spices and sauces before serving. In contrast, edamame is presented fresh and ready to eat, highlighting its status as a convenient option that does not require this additional preparation.
