The Romans did not eat huge meals. Their main food was pottage.
Pottage is a kind of thick stew made from wheat, millet or corn.
Sometimes they would add cooked meat, offal or a sauce made out of wine. Food for the common people consisted of wheat or barley, olive oil. As the Republic grew and the Empire expanded the Romans came into contact with food from other countries. They used herbs and spices to flavour their food and began eating more fish, especially shell fish. Vegetables were plentiful and most of the Roman's recipes included vegetables.
