I am assuming you are referring to the Mopan Mayan people. These are people native to Beliz and Guatamala. Most foods prepared by the Mopan Mayan are hearty, fresh, and flavorful. The mainstay food items of the Mopan Mayan's diet are beans and corn. A wide range of fruits and vegetables are grown for consumption. Some examples are mangoes, bananas, citrus, legumes, tomatoes and onions.
A typical breakfast consists of corn or flour tortillas, with beans or eggs, and coffee. Their midday meal typically consists of chicken with broth and tortillas. Their evening meal is similar to their breakfast. It can consist of tortillas, with beans or eggs, and coffee.
